Did a search and found plenty of info on how to remove the rust but here's my question. Been gathering parts for a while and I'm still about 2 years away from getting serious about this build. The body is solid but a bit crusty in the usual lower areas. Every time I slam the door shut it leaves crumbs on the ground. Is the rust getting worse sitting there? Should I spray it down with Gibbs or something? It is in a heated garage now.
If it worries you, blast it and put it in prime. Its nice working on clean stuff, but for me, it usually happens the other way.
If your not ready to sand blast get inside the doors and vacuum out the rust that's just sitting there and as pointed out by another member,it ain't gonna rust away waiting it's turn. HRP
If it were mine, I'd take my air hose and blow out the bottoms on the doors and other places to get out any***** that may want to hold moisture
You should clean and paint the inside of the body to stop any rust that has taken hold. POR15 or Rustoleum will do. The outside is a different matter but remember, primer is porous. It will soak up water and will not stop rust. Unless you use some kind of rustproof primer, not recommended to do a good paint job over.
Epoxy isn't porous. It's an age old quandary. If you blast it, then epoxy it, then metal work it you get clean stuff that's got primer where you need to work and must remove the primer, work it then reprime it. Lots of times there is hot shards that embed themselves into the primer in hard to get places. They rust. If you blast it, then metal work it, you have clean stuff to work on but it will be rusty again before you can prime it so it usually needs blasted again. If you metal work it first, you work on dirty*****, grind rust where you must also dirty and not always easy to weld, then blast it, then prime it. It's what ever seems like less********* to deal with for you. Every which way seems to have its own special problems. That is unless you have a tv show.
Leave it now. Blast or dip it before you work on it. Keep Gibbs on it till you get to primer and/or paint stage. Best way. TV show or not.
