Simple question that I can't seem to find an answer to.
I am airbrushing acrylic paint on a Batman statue and want to use Testors dullcoat to "lock in" my progress at various staged like so many suggest.
Once I have airbrushed some acrylic, how soon can I add the Testors?
Once I have added the Testors, how soon can I add more acrylic?
Guess that's two questions, thanks in advance.
