yea painting a car is relatively easy, its just tedious work. Jams are easy. The glass and engine are the bitch parts. Is your roof black? or you painting it blue also? All i have to say is "keep sanding". When you think your done, do it again lol. Thats what every boss has told me. I usually sand till my fingers bleed, then stop or tape them up. Makes for leather like skin though.
