It seems that many of the higher-end OEMs are moving to 3-stage paints...I know the Corvette Atomic Orange is 3-stage. The PPG "Vibrance" paints seem to be 3-stage as well.
I have been doing some research into these paints, because there are some colors I really like and they seem to "pop" more than BC/CC. Some of what I read is a little confusing. It almost seems that these are "candy" paints, where a base of silver, gold, or some other color is applied, then a tinted midcoat possibly with pearls is applied over that, then the final clearcoat.
What are the drawbacks to doing this, other than the obvious added step? I have heard they're harder to repair, but I have also heard they're easier to match during repair.
