I bought a can of that duplicolor rust-black primer stuff, and it worked well, my diff colors are no longer crap colored but black! I duno, I prolly have cancer now or someting lol. It said it contained some thing that california says is a carcinagin. Heh heh. Anyway , my question is , do i need to go back and put some of that rust inhibiting enamel coat on? Or just leave itr at black primer on my axles and sutff? thanks 6in 87' K5 w/ 35" BFG muds. 305/Sm465/ NP208 Kn, 4.56's. In desperate need of a rebuild. Next- Eaton mech locker... Flows.
