Painted the car finally - I took two days to do the sealer, base, and clear (It took me nearly 5 hours just to mask and skirt, as I put the car on jack stands). Color is GT Silber. Used (very) $$$ PPG.
Scottyb, you were right about the amount of base. I used just under than 2 quarts for three coats (the cabin, engine bay, and inside both trunks were already done).
PPG does not recommend reducing the clear, but every painter I talked to said to reduce it. Guy that owned the booth said to reduce the hell out of it, and as it turns out, that worked out really well.
I started the initial color sanding with 1000 grit to knock it down before the clear got too hard. Managed to get about 3 1/2 corners of the car complete; then on to the doors, trunks, lid, and targa. I'll do final sanding and buffing after assembly (cause you never know what oops might happen!).
