I?ve been priming my parts as I build and now that I?m working on the fuselage kit, there are parts that will show (right now I?m working on the baggage floor RV12). I?m planning on a professional paint job. For those of you who do this for a living, what should I do or not do to exposed surfaces in the interior that will eventually get professionally painted? Should I prime them? Or send them out to be painted prior to install? Or just wait and have it painted once complete?I?ve been using Tempo aviation primer on unexposed parts after a light scuffing and cleaning with acetone. Thanks
