Wondering if anyone has any advice or guidance....I bought this head cast of a Stormtrooper with a broken helmet and a skull showing from underneath it, awhile ago, from Glassman customs. I finally got around to painting it., with Rustoleum satin white spray paint(with built in primer). Days later, the paint is still tacky to the touch, like there are gases being released, from the resin it's cast in. I even sprayed a coat of Rustoleum semi-gloss clear over it, to try to seal it and it's still tacky, over a week later.
I have had the same problem, in the past, with a Face-Off Incredible Hulk head(Glassman Customs cast head). The hair, on the Hulk head cast stayed tacky for WEEKS, even though I did a bunch of layers of brushed on Tamiya paints. I was wondering if anyone had any tricks or tips on how to stop the stickiness or tackiness??
