Fellas, I am using Eastwood's 2K system - yes it is a Urethane. I am actually spraying just 10-15 oz or less at a time, usually 3 coats. Then going back after full cure and color sanding (yes it is Single Stage Urethane), and then after final block I am spraying the clear coat. No it is not a base coat/clear coat system per se but all chemicals are 100% compatible and things are turning out super nice.

It is a two part system and the paint is not "active" until the activator has been mixed. (no reducer needed as of yet)
