How straight is the truck? Does this repaint involve a color change? If you want a "show quality" job it should involve aligning doors, hoods, fenders and grilles and, if a color change is thrown into the mix, ALL of the panels will have to come off anyways to do a "show quality" job on the jambs.
Like was said previously too much paint can be a bad thing but, if it is in good shape, and the mil thickness isn't bad a "quality" job can be done. If I was spending 15K on a paint job it had damn well better be perfect and that truck would be blown apart and it had better be stripped to bare metal just to make sure it stays that way. No, I'm not picky, 15K is a LOT of money which is why I do my own painting...
