MARTINSR/Others
I have a chance to buy a 55-59 cab that's had all the welding done to fix the usual rusted areas. Body work can or will be completed when I purchase it. The question I have is the cab will sit for over a year before I get to it, so what is the best way to treat it, so that it's not a rust pile by the time I get to it? I want to get my frame completed before I take on the cab. Would epoxy primer work? I need some advise on this as this will probably determine whether I purchase the cab now and have what I want or risk finding a big window a year or two from now.

Thanks,

PS The kids didn't need X-mas present of Santa anyway I have been way better this year.

Epoxy primer is one of the few that actually seals out the weather and avoids rust. Most other primers will be useless.

Most any 2K primer will keep out moisture. I feel Epoxy is the best, but honestly, I have never seen any real study to prove that.

I would etch prime it, then epoxy. The real trick is to be sure it is TOTALLY covered. People have the habit of not totally covering every single square inch with the same film thickness of primer. People will not give it the respect it deserves as they spray it leaving it too thin and it doesn't protect it from the weather.

I have a vintage gas pump in my yard. It was sand blasted, etch primed, then urethane primed. It has not seen one day of cover in 8 years. There is ZERO sign of ANY rust what so ever. So, yes urethane primer will protect. Of course, the etch makes a big difference. But in this case the etch is not exposed at all so at this point it is doing nothing. If it was scratched, then the etch would come into play.

What if there was some bondo left on the body, could he etch over that?
