Cost of a single-color paint job?
If you are not too far from Oakland CA - bring it down and we'll give you a world class job. If you did the bodywork and primer with compatible materials -we would do a final rub and seal, then basecoat (PPG) clear (House of Kolor) on it for you. We could charge time and materials - or just do flat rate. My guess is either way would be $1200 - $1800 materials, and $2k in labor for us to prep and spray, color sand, and polish. You'd have to re-assemble. We have a professional booth and do show quality work.
I'll send you a few pics if interested - just PM me.
