Aluminum HVAC tape, saves alot of effort and last a verry long time as a backer.

[@RaraLovinIt]

Tried your tip and it worked well! I just had to make sure the surface was free of grease and it stuck great.. thanks for sharing

[@irenovatedmv]

Man, I thoroughly enjoyed that tutorial. Gonna watch it again, but this time with my pen and paper to make my grocery list! Gotta get this truck through Maryland Inspection in a few days and that’s the last item on my list and I’m GOLDEN! Thanks so much for taking the time to make this video! 💯💯💯💯💯

[@c50ge]

I like mixing filler on sheet metal, when I’m done I clean it off with acetone or thinner and reuse the sheet metal for a long time.

[@lawrencewessely4587]

Auto Body cock works good for filling small holes like that too in it seals well

[@garrethsmith9954]

I use a mirror

[@Stingyduce]

I use a large metal putty spreader to mix on

[@chrisperez2503]

I just usually sand it down with 80. Been using my pan for a long and was passed down by my dad and he had it for a while

[@jvh22a]

Great idea. Just about to start minor body work for the first time

[@WildWestGarage]

That worked out pretty good. A couple extra steps that might be helpful would be to lightly tap the hole panel to knock off any rust scale on the inside and then tap down the panel a little bit around the holes to get a little thicker patch. Love your channel.

[@PaintSociety]

Great ideas! Thanks for watching

[@Bandit1one]

And use tiger hair glass on first coat

[@thebearsden1701]

I use low expansion spray foam for backing ..as well fills voids so water can't penetrate in...works great .cheers

[@ALexMcDunny]

i can only disagree with you. Those foams are great hard sponges that soak up water and your work is toast.

[@tracilyn4838]

I've watched this video 4, or, 5 times. My 2004 Cavalier needed taken care of (Lower Panels behind doors). Your video has been extremly helpful and the car is looking much better. Though more time would of produced a nicer out come, it is some of the best body work I've ever done. The one of you painting the blue fender is another one I've watched several times and will a few more, as the project is wrapped up. Have a nice morning!

[@The513Warning]

Ayo BRAIN! Not a typo. If you put out a repair/paint manual like Haynes that covers how to paint, prep and fix all paint related issued on all materials, I'd swear buy it in a heartbeat. Your skills are top notch for sure!

[@tosalian]

You are the Best teacher. Regards from Poland

[@chrishawke5016]

Thanks for the info, really helped as I have a 1979 t2 bay vw that needs work and I can't afford it to be welded. I'll keep watching. Keep up the great work. Chris from the uk

[@michaelhasse2568]

I've had excellent results w/ similar rust. Pound the rust hole in, use por 15 & apply in hole w a acid brush & finish w duraglas. Worked very well

[@johnnyblue4799]

At 1:10 I see some holes in the back panel that are covered with plastic caps. Maybe those can be used to access the inside surface and spray some rust converter. Also, instead of cardboard, a clean, plastic dustpan can be used... most people have those in the house I think.

[@sunspiral79]

Best autobody repair videos on youtube right here

[@kodieball2976]

Awesome. Gonna try that this weekend on my rear panel! Looked easy enough.

[@1998232v6]

We just got a Corolla for our daughter that has a rust hole because the previous owner decided not to fix paint damage after a collision… I used for video using rattle cans in the past (2k clear) and it turned out amazing. I love you videos and I can’t wait to tackle this new project car.

[@borgsimpson935]

Great tutorial. Always been thinking of trying some minor body repair. Thanks.

[@Land-of-reason]

Brilliant. Very helpful. I guess Waxoil would be a good thing to spray onto the back. I used some on an MG Midget in the 80’s and it is still going strong in UK weather.

[@RossetBespokeButlers]

This is really helpful thank you. I have done this a few times but your tips will make it much better next time.

[@sst9364]

Thank you for this having a hard time applying body filler to holes and scratches. Glazing putty is what I need. Love paint society! Keep up great work

[@chowchow2386]

Glazing putty is NOT for filling holes. It's used for leveling out sanding imperfections/swirls, and small dings. Don't use it to fill holes, it won't last.

[@HogshooterHotrods]

Great video showing how to DIY that rust away!! Thats the way I learned when working with my dad flipping cars.

[@jasonchristopher2977]

Watch alot and I'm a sub. Love your videos. I've not painted as much as you but I've restored so many antique tractors, oil well engines, Heavy Equipment, Cars, trucks etc. I know a lil bit. Why not use some reformer or acid on the rust you can't get to with a 360 nozzle to kill the rust? At 14 I helped my dad restore a 1949 chevy truck. Under the rear cab window is a seam that is rolled so you can't even get totally inside of it with a sand blaster, which is what we used. An old man told us to use Ospho. Had no idea what that was. My dad used Rust Mort I think it was called, 28 years ago, but thought the blaster was good enough. Was for about 4 years and we noticed rust. Now we used a syringe and Ospho yo get in there and kill it and we did. No rust now for decades. Even if you gotta drill a small hole or larger one and use a body plug and a small brush to seal edges of hole. Just a thought. I see alot of spot on repairs but ppl leave rust, small tiny pits with rust. I can tell you what happens in a few years, especially in a salty environment, if I can't get rid of all the rust however, it always comes back. Always. Acids get a bad name cause ppl don't use them properly, or use on bad paint. Gotta make sure whatever it is to read and do what is said. Ospho has to be rewetted, let sit for a few minutes and then clean with plenty of water and soap if u like. Then dry 100% with air or heat and then spray epoxy, or whatever primer you want. I have engines and autos from 2 decades ago and no rust still. I believe in Ospho and products like it. I also use products from eastwood that make a job like this easier to get rid of or convert rust for a worry free repair. Not a criticism, just a question for you.

[@johndondero8619]

Tx for the video. I’d like to add that I saw plastic plugs on the backside of the panel that you might be able to get access to get a vacuum with a small hose attached to get some rust out and possibly scrape some rust. Also then you can get some used motor oil and spread it around to help with slowing down rust

[@gschady]

perfect timing I'm starting small repairs at home on a '96 Silverado Light Stellar Blue Metallic

[@jimrogers4118]

I like your content where it is just DIY stuff in the home garage. Thanks for posting. 👍

[@shutthetv]

Thank you so much Brian! I'm learning alot from your videos!!

[@carlmccalister4091]

This video brought me back to my roots. Loved the video just subscribed 👍

[@cutlerscrew6]

Guys like this go straight to heaven!

[@richardautenzio8117]

Grest video. Great job. And......I am pleased that you mentioned after all your good work to apply some protective coating on the inside through a small hole on this job. I have sprayed rust converter on the inside before patching to kill any surface rust. And after the job is completely finished I use a product called Fisholine. Fish oil. It creaps every where and retards rust for decades if applied well.

[@socalpaints9718]

Love you new intro ! Still rocking the merch ! I’m also painting full time at my work place now . Thanks to you and the paint society !!

[@PaintSociety]

Awesome !!

[@supercomp7078]

I now clean the area, cut out rust, dent in the edges, use JB weld to epoxy in a steel patch staying under the surface level then fill it with body filler, have used the fibre reinforced body filler to fill holes before as a stand alone filler with no issues and the repair lasted lifetime of car.

[@quentinsomers7614]

Awesome work. Love the channel.

[@patrickpeterman8736]

GOOD JOB LOTS OF VALUABLE INFO; THANK,S BRIAN

[@topcat5988]

I just used this product as well! Works wonderful!

[@waynescott9218]

This has been the best product I’ve found, much like Devcon filler used for aerodynamic fairing on aircraft. I love this stuff for solid repairs.

Great video!! Thanks

[@alexanderstefanxandraswedi5835]

Good job sharing

[@KeanuTC]

Great video! All I can really add to this Is there is some plastic caps you could pop off on the underside ( 1:07 )and spray in some rust inhibitor it's not ideal but it would help seal it up and slow down the rust coming back through

[@jasonchristopher2977]

Yes that's what I asked. I get its a quick repair and not a Lambo but rust has came back to bite me in the butt later and I always kill all the rust no matter how small or minor. In the rust belt if you leave any or bare metal your auto will fall apart. It's a battle.

[@romangranite74]

You don't need to put self itch primer on bare metal?

[@angelmorales220]

[@chadb9661]

@PaintSociety Hey! I have a hole like this in the lower quarter panel of a truck box. Very similar but i have access to the back side of the panel. Would it make sense to use one of these adhesive patches on the inside and leave that patch exposed or how would you cover the patch!? I unfortunately dont have access to weld and trying to avoid replacing the panel...

[@AlexGarcia-cb6uc]

Thanks, good jobs

[@diesel34167]

Greetings from Poland. To make it in accordance with the technology, you would need to spray epoxy on the sheet and then putty on it. It is worth it even if the putty is "water-resistant", i.e. without organic fillers. The use of UV lamps with each application does the trick. Technology with epoxy will extend the anti-corrosion resistance more than twice as compared to putty alone (e.g. Sickens). The basis is: epoxy and a UV lamp.

[@kennethmorgan2704]

Thanks buddy!!

[@Breadmakerc]

I have a rust hole the exact size and shape of my rocker panel… I’m gonna give it a shot

[@tnguyen886]

Thank you

[@juancarlosbonilla]

Very good

[@67cudaksa34]

ciming from a boat back ground, on my farm truck i used fiberglass with epoxy resin to create a backer for larger holes. then used jb weld then filler

[@edwardhalkett9609]

That was awesome...

[@daygoguy1904]

Very nice video. Can this same process be done if I wanted to shave my radio antenna on my fender or the hood washer squirters?

[@sixeight6]

Can I use this bondo to fill small nicks and dents or do I need another filler??

[@chetgingerich2551]

Good stuff

[@garymccloskeyjr.6265]

Brian I had a similar situation like this and the rust bubbled back through in 2 years. What is a product that is a true rust encapsulator that rust won't be able to push back through? Fiberglass resin? Do you have to coat each side of the panel to truely encapsulate the rust. i know eastwood has a product but it is 1K and I don't trust anything that is a 1k for long term durability. Thanks.

[@clarkharvell5242]

I am curious about using JB Weld or something similar on rusty pitted areas that are under trim.

[@royrenelt6181]

Great lesson on home /garage body work, I’m doing a old Kombi slowly with that metal filler,it’s great when carnt weld Any lessons on two tone painting Thanks again Roy from Australia

[@dennisseeker36]

thanks

[@mrshark2443]

What were the items that was not listed like the puddy and the hardener what are they called

[@damensutherland7081]

Do you think it would be better to use self etching primer before bondo

[@eddss123]

Learning a bit from every video. What sanding grit was used to get to bare metal? Thank you.

[@megaman4201]

I believe he said 80, you can go even coarser like 40 if you have it, quicker and better adhesion.

[@gregsantos9731]

Thank you very much for this video, i learned a lot. 😊

[@VolksStokes]

can we use this product on places like firewall? its label does not specify temp-range. thx

[@TonyElam]

Once I do this, how long do I have to get the base and clear coat on?

[@PSP2000MAN]

Kinda disappointed bondo doesn't sell that metal reinforced fillers in a 55 gallon drum for the folks here in the salt belt. Great Video.

[@rodrogers6895]

The back of the quarter panel should have a 1 inch hole with a rubber 'plug'. I removed the plug and sprayed the inside of the outer metal with Eastwood rust encapsulater. It comes with a flexible tube allowing you to coat the entire inside. Other comments below seem to have done the same with different products.

[@Chopski64]

You would be far better off to use panel bond and steel on the back side. Any DIY guy should be able to use panel bond and make it a permanent fix. The panel bond will seal the back side and the filler will actually hold because moisture wont get to it. It also has rust preventive wherever it contacts. This reminds me of the 80's when I did it this way as a 16 year old. Moisture will eventually kill this creating rust around the hole. I know. LOL. I seen it.

[@damxgopak457]

Someone had to say it.

[@woapaggin6803]

So i guess im using the regular one

[@stevofromiowa]

Panel bond is a miracle substance. I know some guys who have even used it for filler.

[@arthurserino2254]

I find a disposable plastic dinner plate is ideal for mixing the bondo.

[@jbeatssnc3368]

Great work thanks 🙏🏾

[@Danyl830wazzup]

I have fluid film at home can I use it instead of cavity wax?

[@demarques1911]

When you started applying the filler over holes .. I started laughing... 😅😅😅😅 because someone recently I knew stripped a Rocker panel down... and when he was grinding.. he saw someone put a 2×4 underneath the body filler 😅😅😅😅😅😅

[@DIYAUTOCAR]

Up here in Wisconsin you'd be able to fit a baby in the hole this is in that area on those trucks.

[@diseld7956]

Very nice demo,

[@SirChevy]

It looks like there are a couple of plastic plugs on the inside of the fender. I'd suggest that it would have been best to remove these plugs, rinse out the inside of the fender with water to remove as much dirt as possible, then use compressed air and a heat gun to dry the inside of the fender thoroughly. Once dry, you could spray a rust preventative/undercoating inside the fender, and once that is dry, then proceed with the repairs you described. As you said, repairing rust holes with Bondo is never going to be a permanent repair, but I think you greatly decrease the chance of the Bondo patches rusting out by doing whatever can be done to clean and protect the inside of the fender. Thank you for all of your videos. I really enjoy them and I've learned a lot from you.

[@userokg751]

Stop being so picky he's just doing an example on how to fix a hole the quick and easy way

[@ALexMcDunny]

My concern with doing rust repair is addressing the inside of an enclosed area. Have you ever injected a rust converter into the area prior to sealing the outside?

[@jeremiahkunze3282]

Can you use spray foam as a backer?

[@anastaseparaskevopoulos4947]

Hey Brian great video. Is the etching can primer a 2k primer as well? Also, if i was to strip the whole car to bare metal, do you recommend guide coating all of the panels or is that just if the panel is uneven? Thanks!

[@PaintSociety]

Etch is not 2k. Just one part

[@supermazingerz72]

@@PaintSociety Hey Brian, how long you think this repair will last here in Florida if there’s no rust in the back?

[@mellis181]

I had similar holes and used this method. One thing I did was spray some rust encapsulator in the holes (Eastwood) to minimize future rust encroachment.

[@stevofromiowa]

Body filler sticks much better when the metal is sanded with 36 grit. With 80 grit, Moisture behind it will cause it to come loose and crack.

[@robd1823]

What was the brand name of the glazing putty?
