The danger of spraying clear over black paint is :
#1, if you polish thru the clear coat, the black paint below will appear a different colour. You have to respray it , the clear coat, again.
#2...Also original type nitro clear, will yellow over time and its not wise to clear coat.
#3...most of the cracking you see on lacquer jobs is because there is too much clear material on the car.
#4 The depth on black and other colours is achieved thru the applying of multiple coats of paint. Nitro is basically opaque and requires a lot of paint to achieve depth.
Yes its much easier to spray base clear coat paints, just not in your garage or driveway.
