What is the "clear lacquer"? Well, it was clear lacquer.... ok, ok..... I'll get serious.

When I first thought to try using those Avery label sheets, I setup a test to discover what clear coating would work. I got a BUNCH of different spray paints. And they all worked. Polyurethanes, defthane, lacquers, enamels...... all worked. None seemed easier to paint with, and all were decently fuelproof within a day. I'm fairly certain that almost any of those mentioned will be fuelproof if allowed to completely cure and are applied thickly enough. whatever.......

If I remember correctly, the UltraKote clear is a lacquer. And the Testors, Tamiya, and TopFlite LustreKote are lacquers.
