Man I have been stuck on the same issue, what to use for a finish. I start with brush on or spray paint base coat over primer, then line work with ink pens and liquitex paint pens. Not sure how to finish. I have 6 or 7 figures all complete, waiting for the finish coat.
What can I use to finally finish these suckers off? I want to keep them from chipping or flaking in the future, and I'd like them to be hardy enough that a damp cloth could be used to wipe them clean of dust once they are on display.
I have a can of polyurethane I am afraid to use. Should I be worried that ink and paint will run as these things dry?
As for the humidity in Florida, the best way to handle that is to move back to Texas. Steve.
