Fair enough mate, I've never properly sprayed anything before but I did my bbs myself. They come up near on perfect, I'd say 9/10
prep work is the major thing making sure every tiny mark/paint/ding etc is gone the spraying is easy
only twit I had was doing it in the garage, was fine till I clear coated and the wind blew some dust over the wheels. can't really see it to be honest but I know it's there so it's annoying
cost about £50 in paint in total, refurb shop next to my work even said they looked really good
