Thanks for your replies, guys. I had planned to do the 3 and 3 (clear) but it seems that 6 coats of clear is a lot to go in the door jambs, trunk gutter area, etc. I realize some would be sanded off in these areas but just enough for adhesion, not blocked and flattened like the outside of the car. Since the car would already be taped off for it I reckon just spray the last 3 like the first 3. Maybe I'm thinking too much about it; just seems like a lot of material in there.
On the subject of painting in pieces, while attending the Goodguys event at Charlotte Motor Speedway I noticed several nice cars there painted immaculately and with great skill and attention to detail but when viewed from the side (front 3/4), the metallic cast on the doors and quarter panels did not match. Straight on they looked fine but as you glanced down the side it was obvious, as if it was panel painted (or in pieces). It was not body proportions throwing off the color either, like when a quarter panel bows out behind a flat door. One panel would appear darker than the adjacent panel. Seen it on a couple solid colors also so it's not just a metallic thing. Please understand I'm not saying it can't be done: just saying I haven't tried it yet and right now can't afford the risk. I'm sure it's done all the time by excellent painters who have the knowledge and experience to pull it off.
