I have to disagree with rt on this. I've had cars done in both single stage and two stage. I prefer the single stage myself. Even though its single stage, the paint is heavier. I like it for touch ups. If you get a scratch I find it easier to match up and I think the shine is equal to, if not better than a two stage. I don't think there is a right answer, it's just a matter of preference. If you talk to your paint shop, they will give you the +'s and -'s of each. Cecil.......
