I enjoy restoring old motor cycles to the point of spray painting. I have used various types of paints over the years: acrylic, acrylic + clear (cob) enamel, enamel + hardener, two pack (mixed). The paint looks great but stonechips can ruin that very quickly. Baked enamel is the next quest for the perfect job. What is the process involved to protect my tinware - primer, topcoat, mix ratios, what temperature to bake, when to bake, time baking. How can I make it as hard as possible to scratch like whitegoods.
