I think Doc mentioned Scalecoat I paint somewhere along the line.
Scalecoat is an enamel, not a lacquer, as the resin film gains its
strength from molecular cross linking. A Scalecoat finish can stay
quite soft for a long time unless it gets an elevated temperature cure
to speed the formation of molecular bonds. That's why custom painters
that use the stuff always bake brass models.
In theory, the finish should eventually cure just as well at room
temperature, but it takes weeks. I've had the bad experience of
rubbing the paint off etched rivet detail a week after the paint was
applied to a brass/plastic composite model I couldn't bake; very
disconcerting. Indeed, I've gone back to mostly Accupaint, which
develops a harder surface much more quickly.
