How to Razor Blade a Paint Run 

From the guitar repair community: a layer or two of scotch tape on the outsides of the blade (in place of the sanding he did) can help you get very close to the rest of the finish to where it sands out and polishes easily. It works better on flatter surfaces than the curved surface that this one is on.

Being a mechanic for over 35 years I have always been impressed in the black art of spray painting, as no one sees a mechanics work, but everyone sees the work of a painter. I have just started to learn spray painting for motorcycle parts...and yes I have a run in the colour coat....I know now how to fix it. A+ for your video.

I was told and also tell others "if you don't get runs from time to time you're not trying hard enough"

Works well when you masking tape the ends of the blade then you can almost adjust the height of you razor to the tee just by adding a extra strip of tape on the ends or removing a strip

Happens to all of us, glad you were able to save it. I hate painting the same panel twice because of a run. Nice job bro

I'm just a hobbyist but this method works good for me too. I bend a gentle curve in the blade & use the outside edge so the corners of the blade are further from the paint. My only worry is how much clear is left and how the durability is affected. Thanks for sharing this great tip!

you are such a genuinely good person thanks for sharing!

The best tool you have is your attitude dont stop doing these videos gab i learn alot from your point of view thx

Great save! Very well done!

Nice nice nice! First of all great beard. Nice mix up from the normal painting video. It turned out great! Caution and patience seems to be the key! Keep up the awesome work. Much love ✌️

ive done that a number of times in the past - it works - but i never realized others did it also

It shows how good your talent is

Fantastic work, well done!

Top job thanks for showing it

Wow .. I've always been optimistic with cutting my runs with a blade .. I learnt alot today ..thanks you

Brilliant!

No man your a proper trainer I like it

bravo, that was nicely done Gabriel!

Great job!

Beautiful, perfect

Well done you😊.A great little video!!

Good job on that run and buff job. 😊👍🏻

Great job young man

Good painter 👍always time to time do runs! We are just a man not a robots!✌

Recently painted and after 3 days of cure clear in my opinion was still too soft to repair a few drips in this way. So you're right it needs to be hard. I have used the razor blade method in the past and it worked pretty well. I have also used a de-nibber on the fine file side, then with a small DA gently used 800, then 1000, and they were gone. Thanks for the video.

Good job bro. You are the best 👍🙏😘

Great save gabe! The amount of jobs you have to do your bound to get the odd mistake! Sometimes if I get a run on a low curve I spray neat blender and it flattens the build up of clear! Doesn't always work but worth a try👍

Good job my friend ,watched the whole video ...

I knew couple painters that have been in the industry for 20 years and they still would make runs lol no one is perfect. Good job with the end result

Great 👍job 👏I really like it

Nice job Gabe

Good job👏

That was awesome bro!

Nice work awesome 👍

Nice video brother, we get those ugly runs from time to time, we're human after all right. Let me give you a tip on the razor blade if you want it. Cutting down the sharp edge is great, in addition what's worked extremely well for me is wrapping the edges of the razor with masking tape, leaving about 2/3 of the center blade exposed. That serve 2 purposes, 1) you cover the edges of the blade to prevent digging and 2) it gives you just the perfect height to glide over that run and giving you peace of mind that you're not going to burn through. I usually do 2 layers of tape and as I get close to where I need to be I remove one layer. God job though, I had all the faith you could do it.. dont beat yourself up so much 👍 By the way where are you located?

Well done matey 👌😎👍🇬🇧🇬🇧🇬🇧🇬🇧🇬🇧

@6:54 HUUUUGE difference the new blade had on that scrape! Amazing to see how worn the edge must have been.

Bro... Dude... Beautiful work well done.... Skillllll !!!

I put but tape on the edges of blade just in case .. get 90 % of the run out then burn throu it’s awesome painting 😂

the oder guy will be happy and luckky with the result from the best teacher

I don't know what is worse, the dentist drill or the air rachet.Rachel. I use a nib file on the radius, it hard to keep the razer blabe from digging in. You just showed that slow and steady wins the race. Nice work.

Sweet. I painted my Vette last spring and have a few runs in the clear, so you've inspired me to try this method. I might add I'm not a painter, just a do it myselfer. God bless

I cannot believe you got that run out. Good job bro

Ive done that lol one thing I do is wrap masking tape on both edges of blade just saying great videos off the panel bet tip ever...I paint for insurance co.clean is a must. Keep up the good work Bartlett collision tx....

Gabriel, there is a much better way to do this which was first introduced to me in a Kevin Tetz Paintucation video. 1)Take the single edge razor blade and mount it protected edge down in a vise with the sharp edge up. 2) Then take a smooth Phillips screwdriver at a 5 degree angle from horizontal and perpendicular to the razor blade and with high pressure drag it across the sharp edge of the razor blade. 3) What this will do is form a burr on the razor blade. This technique has been used for centuries to sharpen cabinet scrapers in the woodworking world. It might be wise to look up sharpening a cabinet scraper on RU-vid to get an idea as to how this technique works. 4) Once you form this burr bend the razor blade with your fingers into a very gentle arc with the center of the blade sticking out further than the edges. Bend the blade so that the burr formed is on the outside edge of the arc. This bending prevents the edges of the blade from hitting the work surface first 5) Use the burr to remove the run. It will cut though the run at lightning speed. In Kevin's DVD he removes the worst run I've ever seen from a mirror in a matter of minutes.

God bless you as well my friend 🙏

Gabriel your funny lol. Great video and work

after you use the blade you could of use dolphin glaze putty over the run then block with 400 ,800,1000,1500,2000,2500

Those curved surfaces are real hard especially at the corner of the fender edge. Nice job. Like you said it is important you let it dry for 2 days as the clear can tear and you need it really hard. The more you try to do these hard ones the better you get. You save the business a lot of money.

Your good real good

I use the same blade as you, little tip tape off the corners of the blade 👍

Hey Gabe how you do that and do cut the paint that is the best tip I for paint runs you do that perfect 👌 thank you 🙏 so much for the video bro keep teaching you knowledge it’s very helpful for me keep it up much love brother Gabe 👌👌👌👌👌👌👌👌👌👌👌👌👌👌👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏☝️💪💪💪💪💪💪💪💪💪💪💪💪💪💪💪💪💪💪💪💪👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏💯💯💯💯💯💯💯💯💯💯💯✅✅✅✅✅✅✅✅ℹ️ℹ️ℹ️ℹ️ℹ️ℹ️ℹ️ℹ️🧨🧨💣💣🥵🥵🔥🔥🔥🔥🔥🔥🔥🔥🔥

great "how to" video. my ol' mentor showed me that trick back in the early 80's. very well done! i had all the fath you would get it out.

hello and thank you for all your videos love them long time fan would you be so kind to tell me the name of that 3 inch air da sander please and thank you

Didn’t think that run would be saved well done pal.

I don't like that sanding block at all but each to their own. I have hard aluminium ones that aren't as difficult to hold and do the same job.

Great

how long after you painted did you wait to cut the runs down and buff out? im a home hobby guy . just painting my own truck (1951 chevy pickup) today with acrylic enamel (PPG industrial, with medium reducer/hardener) and i have a couple runs in the interior paint color. after about 20 minutes the paint is dry to touch. how long should i wait to do what you did here? current weather is mid 60s, going towards upper 60s/low 70s later this week, rainy week in north alabama

Yes, nice video, I have runners too, after 3 basis coat and just one clear coat after halve an hour, is that to short? Frank.

Great work Gabriel! One question, how was this run caused so badly?

What's that red paint color? It's so deep looking!

Nice work! Taking a new razor blade to a freshly painted panel is no work for mere mortals! Would I have burnt through/rubbed through/scratched through? Definitely.

Sir can I share my experience in that situation..I'm not convinced in sagging removal

The fender is a little lighter, but other than that great job rectifying a paint defect.

wrap yellow tape on edges of blade. works great.

It’s only took you half an hour, so to me it’s worth it every time mate

Put that spray gun in quarantine. It has covid. Lol. Awesome stuff brother..stay safe..

Hello! Many thanks! for a very good and Valuable Video. I wonder if, I have got orange peel on the clear coat, after 2 layers. And if I wait 2 to 3 days, and then matt down the entire body part, with p800, and then clean properly, and Add 1 to 2 new layers of clear coat. Is it okay to do that? And if I haven't gotten all the orange peel off after I've matted down the first clear coat. Will it then be visible through the new clear coat? Or what do you think? Thanks! From Tommy Bertilsson from Sweden

I think all the effort was worth it as paint lacquer ect are very expensive. Ian Robinson uk. I did full respray on my red toyota celica.

is that a single stange or base and clear

Hey man, how long did you wait before scraping the sags? The clearcoat seems already very hard

If I get a run I let the clear dry a little bit shoot more clear in that spot let the clear dry wipe a thin layer of Bondo around the run and just sanded out in seconds :-)

Only trouble I found with this method is that the run will have small air bubbles in it. Once you level the run you may end up with cavities in the clear coat.

It's in the clear obviously or is it a 2k finish?(never mind, I just saw answer😁) And what do you rekon bout the putty method? Do you think the putty method over rated for alot of instances. Regardless I am big fan of your videos mate, and the fact you reply to people is a refreshing showing you actually want to teach, not show off. You would make a great apprentice teacher👍

How to fix sagging on the matte clear coat

I call those waterfalls

I don't think it's a waste of time, I always try to scrape and sand any runs away b4 I try anything else, i mean wat other way do you get rid of a run?

With taking so much of the clear off, does this not hurt the finish for longevity?

I have used this exact same method for years and it works. Unfortunately this happens ti all the painters and not every run is the same. The size of the run and where it is ,is going to dertermine the success of saving the panel from respraying it. If the run doesn't have bubbles in it it can be save and I hope you don't go back to spraying in that paintsiut because it is now contaminated.

Hey, what's a good Clearcoat to buy or one that you would recommend and do you have a link for it by any chance

I cut razer blade blocking 600 wet 800 DAwet 1000DA wet 1500DA wet 3000DA wet 5000DA wet and starting buffing idk if iam doing it right but the result was great

And I was wondering if you owned or were boss of that paint shop?

Gabe buffing wearing your paint suit?

Gabe, How do you prevent swirl marks

Can this method be used with single stage paint please?

I always try plan A to C

Tape off the corners on the blade...

Every good painter signs his work lol.. leave the razors and get a festool scraper. They work awesome! 3m makes then and they make runs and nibs way easier

I would off burned long time ago 😂definitely a respray for me 🤣🤣🤣

I operate a mak three

Nice trick are there any more paint suits Xlarge

I paid someone to do a professional painting. He did a good job with the paint but the clear coat at the bottoms of the doors looks like water drops. I got extremely sad. He told me to come back after a week to fix it. How could he mess up like that . I am concerned now whether he could fix that or screw it up even more. Not sure I should go back.

halo gab....y my paint got solvent popping? any solution? gun or my thinner problem?

So when you say “it’s not perfect” are you really referring to the run still being visible? Not perfect means respray?

👍👍👍🚗🔝👏👏

Ay ama 🤦‍♂️🤔🤣🇨🇴👍

Nice save!! You obviously havent got too many runs bcs I dont see many gray hairs on your head. Im all gray and not even 50 years old 😋😂

Yep it`s nerve racking- I Know

nice job on the run, but the color appears dark/greyer than the hood...perhaps more red lighten the value?

so now what? you sand it smooth, repaint that area..what about paint over run to edges where clear-coat is there, now you have paint over clear coat..how you solve that?
