bondo...
i got some spots on my bed where its starting to rust. is bondo really a professional way of repairing it? im sure the best way to do it is replace the whole panel, but can i get a really good finish if i use bondo? the paint and prep will be done professionally by a body shop, but the rust repair is up to me.

bondo is acceptable as long as your not trying to rebuild with it....
think of it as an extremely thick primer, you should only be using it to smooth out rough areas and to fair the edges.....anything more then 1/16th (i think the product says 1/8th) and you need a different method to fix it.......
every single body shop in the US and probably the world uses it...if they say they dont they are full of cacca poopoo.....
so yes, go for it, just follow the directions and take your time, but hurry up....lol

"Bondo" is a broad term used. It's actually a brand name filler that shrinks worse than higher quality products like Evercoat. For pitting that has been completely prepped, I like to use Metal to Metal, All Metal etc. that actually contains aluminum powder. For appling over metal only, not primer and harder to sand, but does a better job. Then you skim coat with regular filler for any minor imperfections and blocking. Filler is not made to fill holes, rusted or drilled. Rusted thru metal needs cut out and replaced and drilled holes welded shut.

We use Evercoat 'Rage Gold' is our bondo as we call it. like has been said many times before, you get what you pay for, i've seen Bondo(actual company product) shrink very very bad before. For pitting we use Evercoat FiberTech, something about putting a filler with aluminum over metal doesn't set well, especially after fixing mirror corrosions on semi-trucks(metal bolt into aluminum, causes corrosion).
Depending on the size of rust spot, at the shop I was previously at we would spot blast the rusty spot, spray a converter on it(PPC Phix is what we used) and tap it in, and start our filler process. Not the 100% right way to do it, but some car dealers want it cheap as possible and don't care whether it lasts or not. Anything through should be cut out, and patched to be done right.

Has someone here used the Evercoat Crome-A-light? I think that's right? Its pretty cheap here. I kind of really like it! LOL Just wondering how well it's going to hold up? It's very light and if mixed correct it does not sag .. I lay it on pretty thick and have not see much in the way of shrinking.
Yea I'm kind of sick and like to spend many hours sanding, ending up taking off about 3/5th of what I put on.
