I sid the same for my 2001 Jeep grand cherokee for the lower rocker panels. Used fiberglass and bondo. Worked great!
it does help to spray inside the panel with zinc primer before doing it, it will last longer
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 !”
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.
Wow, you have a wok truck? A truck just to carry your chinese cooking pot in? That's cool.
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.
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
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
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
at least you didn't spend a fortune in welding then
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.
Not getting rid of all the rust will only return very soon
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😂
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.
Spray foam is a good way to turn rust into rot as it holds moisture. Fix it right and oil it really good.
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
1. It's a farm truck. 2. Spray foam does not hold moisture. Welcome to the RUST BELT.
You're spreading misinformation because that is not true I've been using it for years the rust stops Dead with it😂
@@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.
I think its great work especially your sence of humor. I've even used metal tape below the bodyfill
You are some craic boy. My 16 year old Skoda gonna love that shit.
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
Excellent presentation and craftmanship dude
Foam is oil based. It rejects moisture. Excellent fix.
Looks great from my house !
I've used 'black plastic roofing cement' 5 weeks later it hardened like steel. Good vid champ.
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...
Good video.u accomplished what u set out to do..God bless u
Holes gone ! Mission accomplished ,have a beer
Use kitchen plastic wrap to have the foam cure with a smooth finish.
I'm a 64 year old women and doing better then that.
Lol 😆
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.
I bet u can do all better then our buddy in video😂
😂
It will work for a needed repair,
Yeah it does work but the repair last about a month in the winter time basically the foam is just used as a backer you're better off using a metal screen or you can shove anything in there and fiberglass over it
Where can I get this expanding foam??
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.
Great video!! Thanks
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
I would use foam , flex seal , and bed liner to make it look good
He meant well. But this is not a cure for the problem, it's just a band aid... The rust is still there.
Too bad they didn’t make expendable bondo/fiberglass like that……….
Have you been up in snowing weather??😂😂 NO vehicle makes it without rust🎉🎉😂😂
Isn't the water going to get trapped in there with the foam? This will cause more rust over time.
Almost had me there lmao👍
You sure can but bondo will crack not long after body job is done
In my experience spray foam accelerates the rust so this will last a couple of years then the hole will be twice the size.
I bought a tractor repaired this way, and I sued the guy!!!
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.
Seems legit
They pond and stone spray foam it is wateproof and more dence
Toyota's are well known for RUST. The CAB, BED, FRAME, BUMPERS, and FLUID LINES all rust before the vehicle is paid off.
Not really true
It will come back later. 😂 I cut it all out, weld up new.
It filled the gap in the clear coat WTF.
No you cant fix it in this manner but you can half ass the repair by using foam and making sure its unsafe
You have to use marine Foam
"Fix" rust? no, no you can't
Rust is another name Cancer
Close enough for government work!
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.
what the fuck is it with the noise
6 months and hole will be back
I hope so or, even sooner. I love experimenting so I’d love to try something else later down the line.
Yes, you can fix a rust hole with foam. It will rust out again very soon though.
Just the way you spread the filler on, told me you was not an expert.
Toyotas don't rust? Do I detect a hint of sarcasm?
Really terrible! Is it a joke?
If anyone wants to see other uses for spray foam,go to> www.youtube.com/@JustRolledIn
The foam is basically a sponge, holding moisture and causing the rust to spread even faster. You're bettor off leaving the hole.
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.
@@labooratorija I use foam to seal and insulate houses, not on cars. I will keep using proper materials on cars, not foam.
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
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.
The answer is NO if you live anywhere there is moist ure. 😂get a better job with chicken wire and Bondo.
95 forerunners till 2014 are known to rust underneath!! I put bedliner underneath my Nissan Xterra, that is known not to rust an eighth as bad as the forerunner of years mentioned.
The answer is NO.
Shit filler will crack after coz flex
Hay gm trucks rust out just as bad
No. You can not. It will only make it much worse.
I got my girlfriend some in that big gap filler.
Interesting work…terrible music !
Butcher
This is the worst thing you could do to your cars body
If the rust is a shock fix it the right way not the red neck way little metal rivets little body filler no brainer
Listen anything can rust if you don't properly take care of it.
You need to use some POR 15
