Dash Painting Tips?

I wouldn't use rattle can paint on dash,which is exposed to sun and will fade, I'm sure many will disagree, but I believe in doing things right the first time, also anything that gets painted must be prepped,scuffed,cleaned e.t.c. prior application of any paint .

OP, if you're painting plastic, I strongly suggest using adhesion promoter,there are many on the market, even in aerosol cans like Bulldog, this is a product made for professionals, so you'd have to pick it up at body shop supply store.As for what kind of paint, anything that is catalized,it can be a single stage paint with catalyst flat or gloss or basecoat/clearcoat,which can also be gloss or flat,you can adjust the gloss/sheen with simply adding flattening agent.Catalized paint will be the most durable finish
