Yes, the Kustom Kolors line of House of Kolor paints is acrylic enamel. Some people claim that they aren't *real* HOK paints and that Valspar just tacked the name on for *brand recognition* but they are real, just not the same formulation as their automotive paints. At least according to Robert Baugh at Valspar:
"Kustom Kolor is not House of Kolor packaged into small Glass Jars. There is a reason for this, Urethanes tend not to like Polystyrene and Lexan, plus the solvent package that House of Kolor uses is the strongest solvent package in the traditional Automotive paint industry, This makes the above mentioned plastics turn into goop real nice.
I know that modelers have been putting House of Kolor on Plastic models for many years, but the solvents in them are designed to be sprayed with a respirator and in a paint booth, not in your house.
Valspar took a much friendlier modified acrylic urethane enamel resin blend and solvent package to make a base that would fulfill the hobby industry's desires. Then we placed the House of Kolor Pigments into that base so that the modelers would get the colors that they like.
For the time being the aerosols are acrylic lacquers, however we are moving the chemistry to the same as the 1 ounce liquid line due to the benefits of a reformulation that give the product excellent adhesion and flexibility to plastics without the need to prime."
