How to Paint an Airplane! 

You mentioned 'nibs' originating from your gun, well, you're sorta' right. Your problem is at the mixing bench (I knew it would be). Use TWO (in your case) of the same mixing cups, measure your components in these, primer base in one reducer/activator in the other. Add the activator slowly AS you STIR. Dumping solvents into your base causes over reduction/activation in the center of your cup like an upside down mushroom, then when you stir what's left, the blending can't happen because it's been absorbed in the over reduced part. Thus you have created KICK-OUT, straining will not remedy the problem, you'll have chunks or a seedy finish every time. Also, tack-cloth everything including the air hose (it's likely been laying on the floor). Carry on

Hi, I'm from Costa Rica, thank you for sharing your excellent Zenith work. Thank you.

Finally an airplane paint video! Thank you!

Great seeing the process. The walk through of your materials and equipment was really helpful.

Very nice work, an impressive setup too. Man, you had me laughing at the stack of plastic cups scene!! One of the many things I love about your videos...the little side jokes you play. Keep up the great work...

great vid. Lots of good info in there about painting. Love the mushroom cloud. Got me going for a second

I have watched a lot of your video's. I must say, I admire your work ethic, your tenacity to get things done. I wish I had the same, but I don't have the patience. Great work in all your video's. Continued success.

watching from Brazil, while my skyhawk is being prepared to paint. thank you for sharing uour knowledge

Just what I need to see! Thanks!

Love your vids! I’m ready

Great videos. Just found your channel and watched all your videos. Looking forward to your new build. Thank you so much for taking time away from building to share your experience and educate. Much appreciated!

WOW after 3 years of relentlessly trying to learn about painting i just came across this video. These algorithms are just not doing me justice when i want to find a person whom i can connect with. The other guys i just caint figure out if they are telling us all about painting or they go into so much detail that were not there yet. This was an excellent starting video on painting and do not be afraid about painting.

Your videos are very useful, even for people who are not building an airplane. Good info. Thanks!

Wow I love the way u do your preparation , I am painter in Aerospace company but I really to build my skill because really I love painting thank u so much for the lesson .

Great job... I used to paint motorcycles and looking to fix up a plane soon. Your video was helpful. I also subscribed... your producing quality stuff.

Thanks for the video... done prefectly and easily understandable!

Thanks for the info!!!! Much appreciated!!!

One thing I would recommend is to place a filter on your outlet. It catches any suspended paint in the air and makes you "more environmentally friendly". My brother-in-law does this for his shop and just uses cheap 20x20x1 furnace filters. Enough of me telling you what to do. Thanks as always for showing the process one goes through to go from bag of rivets to flying.

Nice work, thanks!

I’m using the Stewart Systems products for the environmental issues you mention and also for personal protection. Their waterborne products require no nasty solvents or thinners. The nastiest thing is a mild acid, but that is fine to rinse onto the ground as it is quite dilute to start with and more so after you rinse it off. I have only used their single part primer thus far and it isn’t nearly as robust as the epoxy products, but much more convenient to use on the interior as you don’t need as robust a surface and being able to pour the leftover paint in the gun back into the can is super convenient. I will use their two-part epoxy primer on the exterior where the more robust product is needed.

Well constructed video. Good information, good reasoning. I have also used SPI, and love their product. The only question I would ask is, that was a short time before a second coat, that is usually where painters pick up their sags and runs. It's fun at that point and easy to get carried away. Excellent point about the silicon/wax in the tack rag. Do not use the tack rag to clean (i.e. no pressure) seriously just wisp it along. Last thought....use your garage door to practice painting, (the inside portion, duh). Also....H.F. cloth garage makes a perfect paint booth.

Well done!

Nice. Believe me that when you sent your plane to get painted by a workshop, they dont spend that much time into details. They just polish the final paint and thats all. Great job!

I have a LPH-400 😊 love it!!!!!

excelente vídeo

I am building an RV12...contemplating painting it myself because its about 20k to have it professionally done...although penny-wise and pound foolish...important to have a nice finish to a 110k project...thanks for the video...very helpful.

Nice job Mark....can you put something out about keeping your gun clean after painting. Thanks !

Awesome video. I wish you would post your tip size and pressures and whether or not you reduced the primer. I am not a professional painter by any means but I love the 3. accu spray system.

awesome content! look like you are well over your 1000 sub goal. I am getting ready to paint my Cessna 120 and do touch ups on my 172.

Great paint booth set up! I'm aware of your non alodine situation, has anyone mentioned that you should not gloss out your primer? I used to do that with Deft mil primer ( the yellow / green stuff you see on new mil parts). One of my mentor painters was giving me instruction on light primer application. A lighter coat of primer produces a more porus surface for topcoat paint to grip onto ( was the lesson). He was a senior painter so I complied. We sprayed a 1:1 ratio poly top coat. Not currently painting, but hope to get back at it. I'm doing panel removal and installation for hourly inspections at this time. You appear to have a great plan of action and are able to great things. Just a question about you opinion on primer application.

Where does fresh air enter the shop to replace the air exhausted by the fans is it filtered and heated or cooled

Nice video, very helpful. Thank you

Nice job but do I go about painting the inside of an unprimed metal wing from a 1947 Luscombe who’s wings were assembled unprimed as they were back then.

My favorite parts of an plane is the noses they look very cool

If you could show more close ups of the paint being sprayed. It would would be good for me to see what you are seeing as the paint ksyes out on the part

Thanks for the videos, I am learning a lot by watching them. I am also very interested in the Z750Cruzer, and intend to order the rudder kit for Christmas. I live in West Michigan, (Rockford) and would love to visit your hangar someday to meet you and study your build Thanks again for sharing! Andy Greever

Neat !

Nice job, best tip I can give is that the cup lid has a hole on top. Constantly check to make sure paint doesn't plug it up especially when spraying clear coat. If it plugs up you will be dry spraying and newbies think the gun is defective.

Have you looked at the 3M Accuspray and PPS paint system? Very good guns with little cleaning required and eliminate the need to buy strainers and mixing cups. Greatly reduces hazmat waste.

As a long time painter, white tarps give you more light and better color clarity.

What other kitplanes have you built?

Is clearcoat necessary? Are there advantages to adding it?

Amazing timing! I sorted by recently uploaded and stumbled upon your video. I am looking to see what would be needed to paint my Cessna 177 I just purchased. I will have to hire a qualified aircraft painter but will be cheaper at $55 an hour than $12,500 for paint locally.

we just put the polyspray and aerothane on at the crack of dawn outside here in florida when the wind, temps and bugs are down a bit, beware of painting with isocyanates without proper equipment

Great video! After using this system on the Cruzer, do you plan to use it on the SD as well?

Can you paint an aluminum aircraft with automotive paint?

It’s a few years old but great vid

Is the Epoxy Primer you are using a closed cell or open cell primer.....from what I can tell it is a closed cell primer due to your comments on the toughness.....closed cell primers are great but the downside is that unless you apply the paint within hours of applying the primer you may have some adhesion issues with the paint. I think the ultimate is to use the closed cell epoxy primer then a light coat of an open cell primer so your paint adhesion is optimal.

I have watched thru all your painting videos and might have missed it, but what color did you go with your single stage BaseCoat? I assume the color was chosen to match the final vinyl, but am in the process of choosing paint for my product and really like the blue. Thanks

I don't care what the label says, not etching the surfaces will make an inferior bond. You should use an etching solution within a couple of hours of painting. Alumiprep is my favorite.

Wash, then degrease wipe, then roughen with scotchbrite seems a more logical sequence. Degrease wipe probably works best on a shiny surface.

The one thing I see that could be a problem is having the electric fan motors inside the booth area where you will be spraying flammable products.

Hi Mark, how many gallon kits of primer and paint for the 750? Crazy small world as I used to live not too far away in Grand Blanc and Metamora before moving to AZ.

Ground all metal parts before spraying... unless you like static build-up attracting every piece of airborne debris with a mile.

Wow...you must have really different paint than I’m using. I have the Nason system and my ratios are 8/2/1...Paint/reducer/activator. No cooking time. Humph. I’m just doing various parts on an old 182 but it comes out beautiful.

Ok, I’m in process to buy my DeVilbiss paint gun. Is it better to buy the flg 670 or Flg-671 for solvent or water base considering your choice of primer and Nason topcoat? Did you apply a polyurethane topcoat?

Where did you pick up the wax and grease remover?

After you scuff the primer do you need to use cleaner again?

Great video! Can you send me a picture of your attitude poster?!

Is it ok to paint your own plane say it needs some touch up or you want to throw a little paint on it or shall I say touch it up?

Hello Mark! It looks as if you primered the inside of the airplane parts - could you make a video about that? or least comment how you did it and what you used. Thank you! Great videos!!!

You have mention the Blues a few times, any experience with them?

How about a HVLP system? I see these are being used in automotive applications now.

soooooo , you did or didn't go with alidine

Awesome video, we just got a quote to respray our plane, it was big $$$$, I was wonder how much you spent? manly on disposables, looks like this could be done for under $1000 buck if you already have lightly, extraction fans, spray gun, compressor, etc.

whats going on with the can at ? 14:16

Every where I turn someone is saying you have to use alodine on aluminum. How is your paint holding up without the alodine prep?

Great video, and a really nice job on the paint. I’m curious why you didn’t Alodine the aluminum before you primed it. Super job on cleaning and preparing, but after you have cleaned it, your last step before applying the primer should be to apply a light coat of Alodine, especially in mating areas. The Alodine shouldn’t have any effect on your primer, but it does create a protective barrier between the primer and aluminum. It also helps to prevent corrosion. And from my experience, a little reducer will help 8n the spray process, depending on what paint you use. Reducer and Activator are two totally different things. Just my two cents as an A&P.

Why high flow on the air hose?

I'm debating paint vs vinyl...

@9:48. Dawn is chlorinated. Chlorine corrodes metal/aluminum and causes hydrogen embrittlement. That's about the worst cleaner you could ever use.

Hello, a question here. Is breathable air system a requirement for spray painting or a respirator mask is equally good?

we did a painting job to a cessna 150 Trabajo de pintura avion Cessna 150 - A cabeza de trapo ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OgCatuuhGZQ.html

cool paintshop. Don't you want to have air filters to your main air intake vent? Also Wouldn't it be better to have the fan on the intake vent rather than outlets, in order to keep an always positive pressure inside the shop, which would let air naturally escape on the outlets? (this way, it forces the air to come from the filtered intake and not from any crevices and other window gaps which would be unfiltered).

Those gloves don't fit hulk hands... Keep it up, good work.

use you vilbis gti 50$ gun or 1000 $ gun same work can do, or buy cheap 30$ gun or 4000$ gun same work can do, not matter what gun cost. this is true. important lot have you have good compressor and gun nozzle size right. not too big. if can paint home you car you can paint you plane full same tools. only garage need be biggest and old paint need remove outside garage and use chemicals.

Do not forget inside the airframe or you end up in few years with a beautiful plane that is corroded inside primer will do for that nicely.

Money money man

Great video, but I'm sure you didn't know to never use Dawn dish soap on aluminum. First you scothbrited the pure aluminum coating on your alclad sheets of aluminum. Alcoa says the pure aluminum coating is 5% the thickness of the material if it's less than .062" thick. So if you scotchbrite some .020" 2024, the pure aluminum coating is .001" thick. That means you've just ruined / removed the aluminums best defense against corrosion and exposed the other elements in the metal that give it strength, the copper, manganese, and magnesium. Galvanic corrosion is present when dissimilar metals (Remember you've removed the 100% aluminum coating and exposed the alloy elements the aluminum, copper, manganese, magnesium, and other metals) are in the presence of an electrolyte and moisture. So what you've done is opened the metal to corrosion. You see, the Dawn dish soap is chlorinated and when you put chlorine on aluminum, the chlorine atoms embed into the aluminum / alloy atoms and changes the atomic structure of the metal and that causes filiform corrosion. You've put so much work into your painting and I know you didn't know this, but I can tell you this. I graduated at the top of my (A&P) class, my IQ is 140, I also hold other degrees from N.C. State. Other A&P's didn't graduate at the top of their class, they don't have a very high IQ, and they didn't even pay attention in class or read. I've found the OVERWHELMING majority of A&P's working on airplanes don't read manuals, they don't have a fundamental knowledge of material science, they aren't curious and really couldn't care less about their jobs. That's why so many of us build our own airplanes - and I can tell you that aircraft from Cessna, Beechcraft, Gulfstream, etc have rivet holes that crack, they're riviting sucks, their craftsmanship sucks in general - and they know it and couldn't care any less. They're are airplanes out there with a great amount of craftsmanship - some are the homebuilts and others were built in the 1940's If you ever get a chance look at the original riveting work on a B-17, C-47, DC-6 - any of those era airplanes. I could write a book on how bad aviation sucks these days - and maybe I will.

Am liebsten würde ich auch anfangen und mir ein Flugzeug zu bauen,aber mit 69 Jahren= Too late! Shi...

fake or genuine no matter both can paint car or plane good.

You forgot the airplane......

As Paul Bertorelli said in one of his AvWeb Channel videos several years ago: good Audio makes good Video...and this is Not good Audio.

What is this hocus-pocus shit with the paint can, show us how you did that. 14.16

“Getting paint on your parts?” Gross.

Okay, Okay, stop right now, Please, and go purchase a Clip-On microphone set-up. You know, just like Professionals use. You sound as if you are in the Camp Broadcreek (Boy Scouts of Amurka) latrine. I am guessing you can afford at Least a Lavaliere type of you are too penurious to buy a Clip-on.

What fabric are you covering the wings with and will you use the same primer for these surfaces?
