Tired of rust eating away at your classic car? We put expanding foam to the test on a rusty 1989 Toyota truck to see if it's a real fix or just a myth. This video shows you step-by-step how to use expanding foam for a DIY rust hole repair, along with the pros and cons. Learn if it's a cheap alternative to welding, and see exactly what happened to our 1989 Toyota!

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

[@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.

[@marblesrichard]

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

[@tookalook1]

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

[@neilyakuza6595]

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

[@anthonymauger9388]

Holes gone ! Mission accomplished ,have a beer

[@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...

[@jimsix9929]

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

[@terryrideout7457]

Good video.u accomplished what u set out to do..God bless u

[@billmadle1235]

It will work for a needed repair,

[@donnarussell4217]

I'm a 64 year old women and doing better then that.

[@joshlepley1306]

Lol 😆

[@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

[@davidcoleman9304]

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

[@neilwalsh9637]

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

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.

[@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!!!

[@kingtut5923]

what the fuck is it with the noise

[@stevendavis7079]

6 months and hole will be back

[@RusticRevs]

I hope so or, even sooner. I love experimenting so I’d love to try something else later down the line.

[@russellsalvador1620]

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

[@matthewmoilanen787]

The answer is NO.

[@TheGuyOutdoors1]

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

[@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.

[@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.

[@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.

[@joshlepley1306]

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

If the rust is a shock fix it the right way not the red neck way little metal rivets little body filler no brainer
