Can You REALLY Fix Rust Holes with Foam? Watch This!

[@mwh3227]

I tried this with a few small changes: 1) use a rust conversion product to stop the rust from spreading 2) apply foam, let cure and smooth 3) apply a layer of JB Weld, let cure and sand 4) apply a thicker layer of Bondo over the JB Weld, let cure, and progressively sand 5) Prime with Rustoleum 2x paint 6) progressively sand to finish7) Spray final paint color and progressively sand! The foam technique is amazing!

[@misterbojangles6205]

I've used 'black plastic roofing cement' 5 weeks later it hardened like steel. Good vid champ.

[@diverdave4056]

I did a few spray foam repairs over the years on my 2001 Honda Accord ... and it worked GREAT ! I was still driving it with 471,500 miles on it - when 1/2 a tree fell on the roof of my car as I was driving it = TOTALED

[@LordFlashheart1]

at least you didn't spend a fortune in welding then

[@neilyakuza6595]

I sid the same for my 2001 Jeep grand cherokee for the lower rocker panels. Used fiberglass and bondo. Worked great!

[@jimsix9929]

it does help to spray inside the panel with zinc primer before doing it, it will last longer

[@peterszenkowski7769]

this works perfectly fine, i been using this method on my wok trucks for years, all those fools saying it will hold moisture and it will be back in no time have never done this..last time checked rust starts on the outside, foam is on the inside.go ahead go to that body shop and get that bill.

[@herbiehusker1889]

Wow, you have a wok truck? A truck just to carry your chinese cooking pot in? That's cool.

[@Nick-zp3ub]

I'm assuming you live in Arizona or California. In a temperate climate rust often forms from water getting inside the coachwork. Left untreated, the car will corrode from the inside. Especially if it's Japanese.

[@mwh3227]

use a rust convertor prior to using the foam

[@Nick-zp3ub]

@@mwh3227 A rust converter isn't enough. Over time the foam will shrink, tiny water droplets will enter through the gap and the metal will rust around the repaired area. The only way to fix rust holes is to grind out all the rust, weld in a new piece of metal, skim with body filler, sand, primer and paint the entire panel

[@jjm2069]

Yea well this shit doesnt work where it snow 6 months out of the year

[@triedhardbutblessed]

Great tutorial !!! Many thanks and many Blessings to you and to your loved ones!!! I highly appreciate your time, effort and interest to share your knowledge and experience with everyone who can respect themselves by being capable to say at very least, a very honest “Thank you !”

[@Mike-vt6is]

Yep same I add a couple extra steps use fiberglass mat and prime it. Also sand it down before hand with a flap sander on a angle grinder to get the rust out

[@nunyabuziness8421]

For all you experts on foam in the comments foam is a very strong adhesive oil-based and it will not lock in moisture it'll keep it out and it will stick forever and also is a great sound deadener just get some on your hands and let it dry and see how hard it is to get off😂

[@frederickralston1842]

Worked great. I used some wide painter,s tape to hold the foam up in the rocker panel till it dryed over night. Then trim and Bondo.

[@24revealer]

Spray foam is a good way to turn rust into rot as it holds moisture. Fix it right and oil it really good.

[@muddytracker404]

I fixed a geo storm like this and it actually held up for two years. I told the guy it wouldn't last a week. Actually surprised me 😂 I'd lose sleep repairing it with foam now. Some of the local used lots around me actually get away with doing that but most people also don't know what they're looking for. Same as when people panel paint. It drives me crazy. I always point it out and they get mad at me. I just say I didn't do it 😂. People suck doing it that way unless they're just trying to get another year out of it before junking it

[@jamesmahle1259]

1. It's a farm truck. 2. Spray foam does not hold moisture. Welcome to the RUST BELT.

[@nunyabuziness8421]

You're spreading misinformation because that is not true I've been using it for years the rust stops Dead with it😂

[@24revealer]

@@nunyabuziness8421 Don't know where you are, but here in Ontario Canada you do this and it will turn to rot within a year. Seen it wit my own 2 eyes.

[@jimsix9929]

yes it will not last long but to get an old truck looking good I am all for it, yes I have done it before, you will have some bubbles next year but it will be a long time before it looks as bad as it did, can not treat all of these old beaters like show cars, just make it look good for a few years as cheaply as possible

[@jonathonschutt5561]

Literally all I want to do. 91 chevy be rusting hard a Lil bit of this and bondo and fluid spray will do the job

[@tookalook1]

I think its great work especially your sence of humor. I've even used metal tape below the bodyfill

[@JayJay-ii5un]

Foam is oil based. It rejects moisture. Excellent fix.

[@Odipodi]

I've done this before. How i prevent rust from returning is to inject old gear box oil in and around the foam with a syringe. While you're at it, inject oil into your door wells.

[@marblesrichard]

Not getting rid of all the rust will only return very soon

[@deancitroni4447]

Give me some ideas. Thanks! Think I'll take a small piece of aluminum foil to create the profile from the existing good piece add some fiberglass tape and resin. Let it harden and use it as a mold for the Bondo

[@christopherschleeper7186]

I think i would have used fiberglass first. Then, the body filler to smooth it out. But, I get it, it a beater truck and you just wanted to fill the whole...

I’m pretty sure that almost 64 years you were better than anyone around you. That’s absolutely amazing to be able to keep it up with those fantasies for so long. I know you’ll never ever give up on that because you’re the strongest, stubborn woman on that too.

[@tipatlittle2602]

Is it the fact that you are 64 y or that you are a woman that make it special ?

[@aaronchastain4668]

Use kitchen plastic wrap to have the foam cure with a smooth finish.

[@Ozarkfirewoodandlawncare]

Great video!! Thanks

[@HamsterBall-p2y]

Where can I get this expanding foam??

[@31terikennedy]

Definitely use rust converter so everything sticks better. Foam makes a good backer but you could use drywall mesh tape and metal body filler then plastic filler.

[@ravenstone366]

Have you been up in snowing weather??😂😂 NO vehicle makes it without rust🎉🎉😂😂

[@billmadle1235]

It will work for a needed repair,

[@shields_movers]

He meant well. But this is not a cure for the problem, it's just a band aid... The rust is still there.

[@KadeStringer2.0]

I would use foam , flex seal , and bed liner to make it look good

[@dalehammond1704]

Actually your body job looks better than a big nasty hole. And it probably will help preserve the truck. Nice work I say. The catastrophic increase in repair/body shop charges the last couple years means DIY or hire some local person who does repair work on the side at a bargain price (they're out there). It's either this or go without. Times are tough, especially for young people. Nowadays it costs $70 in our area just to have a garage check your car out. A few years ago this was free. Videos such as this help a lot of poor people.

[@Timmy-h4q]

Seems legit

[@Sigspearthumb1]

I've heard if you put tape across the hole after you reclear coat with the foam, when you pull it off, it'll already be straight and flat.

[@patrickstarnes2355]

Read the cans instructions Turn the can other way up !

[@michaellambert5223]

Tape a hunk of wax paper to kinda form fit then shoot foam in a hole ya make. Think injection molding 👍

[@johnmorrison1180]

In my experience spray foam accelerates the rust so this will last a couple of years then the hole will be twice the size.

[@garybulwinkle82]

I bought a tractor repaired this way, and I sued the guy!!!

[@neilwalsh9637]

Too bad they didn’t make expendable bondo/fiberglass like that……….

[@howardsmith7950]

Almost had me there lmao👍

[@blueovalfan23]

seems like that would trap moisture. i'd think a fiberglass patch coupled with body filler would be the better fix. i guess if it works, it works. personally though, i've been more fearless in terms of ability. i would encourage you to do the same. buy a welder and figure it out. that's what i did. turns out, it's not that hard to do. i'm not a body man by any means and welding with a flux core on 1/2 rotted sheet metal is an artform more than a skill. after ya get the trick though it's simple.

[@Knowbetter69]

Listen anything can rust if you don't properly take care of it.

[@Knowbetter69]

You need to use some POR 15

[@deanwattles8722]

"Fix" rust? no, no you can't

[@davidcoleman9304]

Toyota's are well known for RUST. The CAB, BED, FRAME, BUMPERS, and FLUID LINES all rust before the vehicle is paid off.

[@KadeStringer2.0]

Not really true

[@urignorance2922]

They pond and stone spray foam it is wateproof and more dence

[@Dukerdr]

When you start a video by saying "Toyotas aren't supposed to rust...", I can tell right away either it's a parody or you don't live in Ohio. I've seen lots of Toyotas rust. Nissans too.

[@dha588]

Isn't the water going to get trapped in there with the foam? This will cause more rust over time.

[@RyanLindahl-u5l]

You have to use marine Foam

Rust is another name Cancer

[@mecanicman66]

You sure can but bondo will crack not long after body job is done

[@matthewmoilanen787]

The answer is NO.

[@SamusMaximusSMXD]

No you cant fix it in this manner but you can half ass the repair by using foam and making sure its unsafe

[@the1andonly]

The foam is basically a sponge, holding moisture and causing the rust to spread even faster. You're bettor off leaving the hole.

[@labooratorija]

I think you know not much about a foam. Or your knowlege is a bit too old. Theres a foam for outside use, even -30, +50. Ppl use it to isolate windows, or smth like that.. you can spray it on the ground and come to check 1 year later. Then you see that its not like a sponge. And if you cover that foam with rubber, or fiberglass, it can last for very long time. But you need to remove old rust as much as posible.

[@the1andonly]

@@labooratorija I use foam to seal and insulate houses, not on cars. I will keep using proper materials on cars, not foam.

[@Drop_N_Chop_LLC]

You can use foam as a replacement for concrete on post . I don't think there is anything wrong with using this as an alternative on a budget . Get it looking nice and sell it to someone else ​@@the1andonly

[@peterhallock9486]

It filled the gap in the clear coat WTF.

[@danieltaylor4819]

Yes, you can fix a rust hole with foam. It will rust out again very soon though.

[@kengrimsley4172]

Close enough for government work!

[@joshlepley1306]

No. You can not. It will only make it much worse.

[@herbiehusker1889]

Toyotas don't rust? Do I detect a hint of sarcasm?

[@ericdoris8852]

Nope. The foam traps moisture and rots from the inside out. No different than armor guard. Moisture traps behind it and rust starts. Stop trying to do it cheap. Just do it right.

[@TomJohnny-zz4dp]

What's the biggest butcher job you could ever do😂

[@russellsalvador1620]

Just the way you spread the filler on, told me you was not an expert.

[@miltonbiletski278]

Why do you call it a fix when it’s a band-aid for a month or two? I’ve done bodywork for 40 years and it always comes back just like the cat . Ive seen everything anyone has tried to do . Just go buy a new panel or pay the price to have a pro make it

[@petroflorence7962]

Shit filler will crack after coz flex

[@williams6756]

Hay gm trucks rust out just as bad

[@BR-ho8nk]

Really terrible! Is it a joke?

[@Nick-zp3ub]

Foam filler blows out after a few months because it holds water and will corrode the remaining sheet metal until it becomes brittle. The only way to fix rust is to cut it out and weld in new metal

[@pyrpuppies]

I got my girlfriend some in that big gap filler.

[@TheGuyOutdoors1]

The answer is NO if you live anywhere there is moist ure. 😂get a better job with chicken wire and Bondo.

[@tonyfurneaux3399]

This will last five minutes if you are lucky, get rid of this truck. You did not allow for thickness of filler, or should I say thinness, where is the strength...Just saying, also foam holds water, so will make a very bad much bigger hole soon.
