No primer unless its rsted as high as the paint its basing! Wallymart BBQ paint, or i had great results with UHT ceramic white, but with most header paints, you need to paint them and instalk them as fast as you xsn so you xsn run them to cure the paint per instructions. Otherwise you just get silver psint thst cones off on ypur hands ad soon as you touch em. F'n tablet keyboard, im not this bad of a speller!
