It has been a while, but I had Eugene paint mine when I had the enclosure done. I believe I paid $450 for candy apple. That cost only included painting, it was up to me pick up the body and install myself.
Eugene's Quality Golf Cart Enclosures
My dad had two carts done by Eugene. Most of the guys that refurbish carts along 441/27 have a painter they use. May be worth a call.
