Hello I would like to paint or coat my rusty exhaust manifolds . Has anyone tried some of the stuff in spray cans available at the parts store thanks in advance 

I'm a true believer in using a ceramic coating - save up and do it! You won't regret it for a minute. This set now on my bird - was done by "Jet-hot" in aluminum finish, inside and out. They also offer a color that looks like fresh blasted cast iron. High temp resistant - and as advertised it lowered the underhood temp of the manifold by a couple of hundred degrees.
