if its giong too be under high heat ie a rocker cover normal paint is ok only if its two pack! but if u go to B and Q u can buy a paint called plasti kote its a very shiny hard wearing heat proof paint that sprays well too (comes in a spray can) also in lots of colours mate and they do a primer so u can prime it then wet and dry it nice and smooth they also do a lacquer gives a really good finish
