I'm only doing my very first rebuild including paiting on an old guitar of mine and I got ahold of a friend of mine that has painted many cars and has all the stuff to do it, I think that is the only way to get a good paint job is to pay the cashish and use good car paint. We've layed down two good coats of dupont primer, sanded it with i think 1500 or 2000 grit and then layed down two bass coats of the bass color then cleared it and it looked great. However we planed on sanding the clear at that point to take out a couple specs of dust but have found that we have to start all over because of a seam that showed up after it sat for a while. But up to that point the pait job looked like it did when i bought the thing, paint it like you'd paint a car.
