Are they enamal, lacquer, or acrylic paint?
Here's what I got from Kustom Kolor:
[FONT=Verdana, Helvetica, Arial]Here is a conversation that I had with a gentle man named Marcus that had asked that very same question. I hope that this answers you question. But for the quick and Dirty answer it is a modified Acrylic Polyester.

[FONT=Verdana, Helvetica, Arial]Marcus:
The chemistry is so unique that can not be classified a just an Enamel
or Lacquer, Acrylic or Alkyd. It is a complex Hybrid, the closest
description is an Acrylic Polyester, but that is still not quite right .
It has characteristics and properties of all those chemistries.
To my knowledge this product doesn't have toluene in it, I however would
have to confirm that with one of our chemist. I can provide you with
MSDS sheets on any of the products if you would like, I would need to
know which products you are interested in.

[FONT=Verdana, Helvetica, Arial]Your label says it contains xylene, a substitute for toluene which makes
it slower drying. Xylene is closely related to toluene. By definition,
lacquer is a paint made from various materials but containing a volatile
solvent. Since it contains xylene, it is, by this definition alone,
lacquer. Because it is slower drying than most lacquers (because of the
xylene), it dries with a greater gloss, obviating the need for a gloss
clear coat over it, thus it is an enamel. Do I have this correct?
I have been treating it as a lacquer with nice results on plastic. I use a
medium temp lacquer thinner for airbrush thinner and it works perfect. I
mix it with Testors Model Master lacquer and it blends smoothly.

[FONT=Verdana, Helvetica, Arial][COLOR=[COLOR="Silver"]#0000ff[/COLOR]]The widely accept difference between Lacquer and an Enamel are the process by > which the paint becomes hard, cures or gasses out. You are correct that many Lacquers have fast acting solvents with high levels of very quick tail solvents, AKA they dry really fast leaving a lower gloss rating. However, that is not the only defining characteristic of a Lacquer, it would also, deal with shrinkage, hardness and the ability of one layer to flow into another one, BLEEDING. Lacquers are also, more easily re-constituted into their original form because of their susceptibility to aggressive solvents.
Now on the other hand you have enamels that dry not just by evaporation, but by a chemical change as the solvent leaves the resin. This process requires a slightly slower solvent; yet it gives you a stronger glossier appearance. However, the more aggressive solvent will attack this semi-permeable surface and could cause wrinkling it the chemical process is not complete. And the surface finish is dependent on the speed by which the solvent leaves the resin, orange peel.
So, to get the benefits of both a lacquer and the benefits of an enamel we where able to to find resins that had the ability to cross-link, enamels and lacquers. These resins are of course propriety to our product line. They do however allow for an extreme versatility in application and mixing ability. But stronger solvent packages with higher biting qualities are required, Xylene is the one that was chosen.
I hope that this is helpful and answers you question,
