Hi, guy's, got my pickup to work on, the title says it's a salvage, and o boy, this thing is sporting at least a half inch of bondo. It was all cracked before I got it, so I'm stripping it and it appers that someone bondoed over major rust, so I'm grinding and wire wheeling it. My quation is should I use self etch before bondo or bondo and go with epoxy? I'm kind of doughting I can remove every tine bit of oxidation.
So are you planning to strip away the old bondo, which was put over rust damage, only to replace the bondo without repairing the base metal rust damage? Just wanting to understand the basis for your questions.
The truck is stripped 80% now. but the rust is pitted pretty bad in some places, I will grind and wire wheel all I can, but to be honest I'm thinking getting it 100% is going to be hard. things like inner wheelwells, wich I would like to seal and paint, rusty cuts in the bed.so it will be close but I was thinking I could get away with a little imperfection if I used etch before bondo. Thanks
I'm I think with Roger. Why not replace the rusted metal? If not all, a lot of it is reproduced and not that costly. You have pictures of what your doing?
They've got patch panels for about everything on that truck - https://www.google.com/search?q=1951...sm=93&ie=UTF-8

I don't think etching primer will even stick to bondo. I have always used epoxy primer first, that way it seals the bare metal and then you can start the bodywork cause bondo will stick to epoxy.
But I do agree that replacing the metal then using bondo sparingly to smooth things out is the better way to go.
