Ads, I have a friend who is a sprayer buy trade (that's his 9-5) and he laso preps and sprays cars for the hot rod/modified car scene in his spare time. He has a unit on an industrial estate with vented spray booth etc.
His portfolio of work speaks for itself, he does a lot of trick finish/metal flake/metallic stuff, as well as standard paint finishes (the bodywork on his Mk2 has to be seen to be believed!)
I'll speak to him tonight to get a guide price and lest you know on sunday, but obviously it will be a bit vague until he sees the car and can work out what materials and prep is required.
