Eric, that seems like a bargain to me. I've been toiling on the paint and bodywork of my fastback for about 18 months, so $2,800 seems very good. If I were you, I'd ask to see some of his past work and maybe speak to a past customer or two, if you can work that into a conversation without putting the guy on the defense or offending him. I'd also ask if he uses single stage paint or basecoat/clearcoat. While single stage is fine for solids, for any metallics I'd go with bc/cc for their ease of touchup. When you consider that materials can easily go for $1,000 (filler, primer, sandpaper, reducer, paint, etc) a $2,800 job is a rare find. Also ask ahead of time if he plans to remove the trim around the windows, paint the jambs, and so on, since many shops don't unless you specify. Good luck and post pics!
