Title says it. I'm gonna begin frenching my rear springs next on my 81 pu build. Afterwards I plan to sandblast my frame atleast from mid cab back. It's a very solid frame and I wanna keep it that way. I know they ussually rust from inside out, I'm also doing this for looks. I've seen and heard of expensive paints that are supposed to be good. My question is what is best?? Since it will be blasted to bare metal, I will need to paint it right. Hopefully in the future I will blast and paint my axles, after "hopefully" shaving them (someday)

 

I've never tried it but everyone seems to like this POR 15 stuff :http://www.stoprust.net/

 

I agree with mt goat. POR15.

A little expensive, but worth it for the protection.
