I wouldn't see why you couldn't sand the base, unless the paint
manufacturer requires the clear to be layed down before the base could be
sanded. Using a few different PPG systems, I've found that I could have
time to sand the base, even though the clear was supposed to be layed down
within 8 hours of the base. I've done some flames like this where I layed
a base, then waited a few hours (or even a day) and masked out flames.
Then I layed down the flames and sanded the base coats to blend the edges
of the flames (so I didn't have a sharp transition between the flames and
the other base coat). I waited some time then applied the clear over
everything.
I think the best way to find out is to talk to the guys at the paint store
and tell them what you want to do. I'm just telling you what I've done
before...
