restoring a dash

I,m a painter here in Australia but its the same principal, use a Scothbrite (3M $1.50) pad with warm soapy water or Auto scuff paste to take the sheen/dirt off to give it a good key then wash with clean water and blow dry or stick it in the sun,Prepsol or wax n grease remover to get rid of ur greasy paw marks then get some platic primer/adhesion promoter then a quick coat of primer and smash some paint on, JUST TAKE UR TIME,too much paint isnt a GOOD thing, let it dry a day or two if its cold before install :)
