I cant imagine rolling, then sanding off 30% of every coat (at least) is not wasting product. Use a small detail gun...turn the pressures down. I've sprayed sections of cars with spray bombs before. So I'm not bashing the "cheaper" concept.. Just the lack of ecomony in time and material. I can spray a car with decent materials with 2 gallons of product, even cheap automotive type paints (say $40/gallon), and about 10% of the final coat of that will be wet sanded or buffed away. Sure, the paints $20/gallon. But these guys seem to use more than a couple gallons in the course of the 7 coats. I think a cheap paint sprayer woudl really make it easier. But I can see where the guys in appts might have a problem there.
