SHAKEN OR STIRRED? POR-15 Mythbusting - ONE YEAR TEST!! 

I've watched your older videos on this. For the extra cost and steps I believe there is a better options. And my two young boys laughed when they heard shake shake your booty. That's what we used to sing when making them chocolate milk.

And this is why reading the instructions is a waste of time. Learning stuff never changes the outcome. Thanks for the update!

Great follow up to the follow up video to the first video LOL. Very helpful and THANKS for putting up with the jack wagons and the "real world" test. Very helpful!

I learned this mistake as well. I bought the Por-15 rust preventer in clear & shook the can for a while. When I opened it there was tons of bubbles seen throughout the whole can. When I painted it on there was bumps all over. Had to redo the whole project. I had to wait a couple weeks for all the air to come out the can and this is the reason you can't shake it!

Thanks for the test! I used POR-15 on a rustee battery tray in my car and unfortunately the rust came back within 3 years. Thought I did something wrong and was going to try it again... This time restoring my e36 M3. But, since watching your tests, I will be using Eastwood after some cutting and welding. Love the T-shirt btw!

the commitment to this project tho. 👍 thanks for the continued followup

Awesome job done on this video and much appreciated!

Damn I hate instructions. Good job keeping your cool reading that confusing crap!

Other than house paints, most of them specify to stir, not shake. With 2 part paints, the air bubbles are actually adding a 3rd part(02), or diluting what the mix ratio is, giving inaccurate quantity measurements. Plus all the bubbles are just a pita. Other than the bubbles making for a bumpy texture, POR is activated by air so if there are air bubbles in the unused portion maybe it will ruin it while in storage? It’s odd that both sides of your test where bumpy tho. Usually the POR will self level and be smoove, even brush marks are usuallly disappeared.

Oh yeah, I’m gunna put six coats of paint on my frame 🤣🤣

We did a frame rail after putting on a paint shaker. It did have tons of bubbles. I don't think it will matter on a small area, but a large area will come out better if not shaken.

many products don't want a shake as doing so introduces air bubbles. if you do it with polyurethane plan on sanding back to bare wood and start over.

I think I saw your hands shake a bit when taking it out of the box in 2020. See you in a year.

I have been undercoating my 30 year old truck with por-15 since I bought it. I never read directions and shake it every time. My bad. But the stuff work pretty well and it's easy to touch up my sliders and skid plates when rocks cut through to the metal. Rust-proof is a misnomer, but I think it's helped preserve the nuts, bolts and threads under there so they are intact when I need to work on the truck. Will stir going forward...

Can't argue with a test like that.

Great Job and Commitment. New Subscription for your effort and informative videos\!

Good video. Technically though, doesn't a shake after a stir create a third alternative? I assume it wasn't a long time after stirring before you shook the can so hardly any difference. I wonder if shaking is an issue when a can has been sitting for a very long time. It's not like a rattle can so settled contents may not mix properly if you just shake the can. I think your shake after a recent stir negated any issues.

I've gotten serious bubbles from shaking. I could see them in the paint when it dried.

I shook the heck out of the stuff but then I also sprayed it through an HVLP gun with a screen cap. Yep you can spray POR-15. I bought some POR-15 solvent (it's just naphtha y'all) and sprayed a cleaned up (per the POR-15 clean/degrease/etch gospel!) skid plate. Two coats took two 4 oz cans but that coating is thick and shiny and is hard as porcelain. Will it last? Who the hell knows. But it'll certainly last longer than the flaky rust that was there before would have.

the do not shake is just to keep the air bubbles to a minimum. Has nothing to do with how the paint actually works. The inherent problem with POR15 is it has way too many steps and directions. Its very hard to do correctly, but works great when you do.

I use to paint for a company that used POR15 on all their chassis and under bodies. Threw away lots of new cans because of separation. You can't stir the brick at the bottom of a can.

As I mentioned on the previous vid, shaking is likely just about air bubbles during application. Should make almost zero difference especially with multiple coats. This process is so complex it only makes sense for very small projects. Especially given the expense. People just really want to defend POR. It's not automatically the best product just because it's the most well known. The little bubbles in the finish are strange as well. Good testing. Hopefully this quiets a lot of people. Sunk cost bias will keep them defending though.

Lol glad to stick to the results. Do you have a year 3 update on the others?

Thanks for doing all that work! After watching the 3 vids I decided to use ACE on my Jeep's floor pans (it's holding up well) Now I'm planning to do the inside of the frame with the Eastwood (considering using Evaporust or similar first, it's pretty rusty)

Maybe the stir will let you know if any solids on the bottom you can stir out

Just seen this excellent video. Here is my take for what it's worth. After reading and researching on the net I decided POR15 was the way to go. I refurbished some suspension items on one side of my car. I had them sandblasted, I degreased them to death, used the POR15 metal prep, used the paint, 2 coats, exactly as per the instructions, they looked great. 2 years later I decided to restore the car, so the entire subframe and suspension had to come off. The POR15 parts looked just like they had come off the Titanic!, the untouched original 22 year old parts looked great by comparison. POR15 is over-priced garbage. Everywhere I have used it it has failed. There are far better products out there.

I'd like to know what solvent to use if you can send me where I can get them in the name of all of them

It also says store unused portion in the refrigerator....YA RIGHT!!! Like ANYBODY"S wife is gonna let that go down!!

helpful 👍

God Bless you too man! Thank you for making this video! Hope to see you doing well! A reminder for anyone who may need it. Dont forget to read the Bible!

James Bond "Shaken ... not stirred"

Of course it get shaken a lot before you buy it, but it should not be shaken just before use. POR suggests that you stir it, but don't open the can(??) I would shake it several days before using it and then before punching two holes in it to pour some out I would gently flip it over a few times.

You can spray por 15 with an hvlp gun and doing so will put air in I don't understand

Hilarious Well Done

guy pulled out the rustoleum primer and i left.

Doesn't it get shaken during shipping?🤷‍♂️ 📦

i bought a big can of por15 and open used some then closed lid and stored it, 2 weeks later the whole can dried out. now i bought my 2nd can and leared from some video not to open lid but drill a hole ,pour some out through the hole then seal it with a bolt,it works great i dont have to worry about the paint dry out in the can. BUT, i lost option to stir it.

Hi how come you didn't test RustBullet, it does need any prep other than removing loose stuff and doesn't need top coating and is not UV sensitive. Cheers

The only problem with shaking is simply the bubbles it creates.

Thanks!

what about the first test, should have been at the 3 year mark yeah?

I had a white bottle and shook it hard and it frothed it which made it a real pain in the ass to apply on the metal. There were tiny bubbles everywhere. DO NOT SHAKE IT. In the black you did here didn’t seem to matter too much although wasn’t a very nice looking piece of metal so hard to tell. In my case it ruined the project. Foam roller doesn’t help either. I went back and dragged the bristles 45 degree over to help pop some bubbles Nice test. And actually waiting a full year to school the trolls haha.

is that the same can you used in the 1st video

The more I watch these por15 videos, the more I think about not going ahead with por15 on my Jeep. Epoxy primers look more bullet proof and longer lasting.

I first used POR 15 about 30 years ago and many, many times since. If used as per the instruction, it is a brilliant t product. Shaking the can causes air bubbles, which can cause bubbles in the final product. "If all else fails, follow the instructions". If you don't like following instructions, don't use this product. If you do follow instructions, there is no better product.

Is KOR better then TOR?

Technically you stirred both then just added a shake to the second one 😂 there are lots of solids in the bottom that shaking won’t get them back into the mix

STIR CONTENT THOROUGHLY BEFORE PAINTING. DO NOT SHAKE. I guess they expected you to read the instructions and comprehend them. If ya have to as your father ask for an explaination.

Bubbles in the finish aren't just cosmetic, they are an area where the rust prevention is decreased. I have been seeing more and more videos where the person doesn't bother to read instructions, but then goes to teach us by video. Sorry I know that sounds harsh.

The right Twix

In my opinion Por15 is garbage I’ve done their bs prep I have followed their directions to a t pamphlet in hand as I’m painting the only stuff or rust paint that really works is RUST BULLET I work in rock quarries and my truck frames were rusting away so I picked up a computer and got on interwebs I researched and researched and I stumbled across RUST BULLET a industrial rust encapsulating paint it has three steps prep base coat and top coat the only thing I do different is where two pieces are riveted together I use rust converter like where the cross member meets the frame I take a foam paint stick and slobber that converter in the seams the other thing I’m doing is once a year I pressure wash my trucks underside and then use fluid film frame black to get inside all the nooks and crannies the door bottoms can corners cause The price of 1 ton trucks is crazy and I’m not shelling out 85000 for a truck every two years that’s just crazy and by doing my rust irradiation program I’m working on 4 years and still have no rusted rotten freakin holes in my frames let me say this again POR15 sucks might as well use my kids finger paints in school RUST BULLET is where it’s at it’s an industrial high solid coating and it works

Don't they mean a paint shaker?

A great job you have done with these videos........BUT........ you need to get a PAINT THICKNESS GAUGE so that you can determine if you have applied the manufacturer's recommended thickness of the coating............... you need to eliminate the variables and unknown factors to make a proper scientific test.

the results are crap compared to what they promise, the rust is coming back worse than before, i wouldn't use this stuff at all!

I am sure the can shook on its way to the store and your home.

The perfect amount of salt.😂😂

I have a tj frame that I had out side in florida for about 2+1 year, my preparation was Like wire brush it and clean it with dawn dishwasher soap, alcohol as the last cleaning method, and then paint it with pro15, this thing got hit by one of the hotter heat in florida now is been sitting into 2023 in NC for a year, and this frame is beautiful as the 1st day I paint it, now to install I'm now buying the pro15 for my engine, not waiting anymore time to ride my TJ. just to say this product is great at least for me it worked no complain very happy with it.

Lol

This s*^t is to expensive!

POR15 is just massively overrated in imho.

Wish I had seen this vid before a wasting truck load of money on pour 15 products, not even going to use what I brought now, think I’ll just sand off rust, neutralise rust, then use a good two in one enamel. Crappy overrated product.

this is why you don't listen to guys like this

Por 15 is trash either way. Ive done prep after prep, tried and tried. It falls off in sheets and has a list of things a mile long not to do to the point you cant help but question the practicality of using in the first place. I shouldent have to baby something the price of liquid gold that works worse than a cheap can of rust oleum spray paint.

por-15 is garbage, I've used it many times many different ways on my semi trucks. Better products exist.

Rust encapsulates are a waste of time. Some brass brushes and attachments for a drill and you can just strip the rust in a little bit more time and way less cost.
