I'm a cheap garage spray booth guy - personally, I like tcp global's acrylic urethane single stage - sprays and color sands like acrylic enamel - In fact, better than my experiences with Dupont Centari AE. I painted the exterior of my '53 truck with 1 gallon yesterday (4 medium coats) - good coverage and good laydown with a little extra reducer - This is the second time i've used this product with good results. You can buy 1 gallon of premixed color (gallon of color, quart of hardener, quart of reducer) for about $100+shipping.
