Cody,
I agree with the others, spraying it is not hard, but you do need a decent spray gun and it needs to be prepped properly and really really clean.
I sprayed some door panels to match seats I put in a street rod and it turned out near perfect right out of the can, no thinning or mixing. I also agree that if you are to do it, you need to buy the die from a reputable auto paint supplier.
It will also mean covering everything in the bus as far as walls, furniture, and those beautiful cabinets you made with plastic drop cloths or something similar. You will get over spray.
