The pigmented material is actally plastic suspended in water which
then evaporates.


But the water-based car paint has to be protected with a clear
laquer coat, or it would not last very long.

Dulux Weathershield is still solvent-based, top coat and
undercoat if you buy the trade variety, but their matching primer
is water based and very difficult to apply to hardwood or any
wood with previous coatings.
