I had my rig painted in Mexico. Ours was painted in a booth, also stripped down sanded and primed. Using RM paint by BASF that was not water based. The pearl white was about $200.00 a gallon. There is very inexpensive Mexican paint that will not last long. Most painters around here use Dupont which is middle of the road. The clear coat is the most important and should have at least 3 coats. We paid $8000.00 five years ago.
You will get what you pay for!
