If I want to use these, should I get them media blasted and ceramic coated or just hit them with some high temperature paint?

They look to be in good shape. They were last on a car in 1977 and for not that long of time.

I am not rich...but I get off my ass everyday to make sure I am not broke!

Can we get the Mexican cartels to help us with our supply chain issues? They don't seem to have any trouble getting stuff from one place to another.
