Waterbased paints were introduced in model year 1991 in order to simplify the painting process and to reduce weight.
Water based solid colours to the best of my knowledge were not given a clear coat.
UN is the interior colour code combination and has nothing to do with being clear coated.

a) it's Water-based
b) Not Clear-coated?
c) if you have a choice of water or solvent based (perfect world), what would you choose?
