If it is the aqueous stuff, watch out!
Even when well cured the Testors Glosscoat in the spray can will dissolve/soften/ruin it.
I can't tell you how many times I have done this, forgotten which a/c or armor I have painted with gunze, gone to gloss coat for decalling and ruined a paintjob.. Too many times...
For airbrushing it, I've never had a problem thinning it with rubbing alcohol and cleanup is a breeze. I have not had much luck brushpainting with it, it's a little thick and takes FOREVER to dry.
