I bought a 28mm resin bunker and washed it several times in detergent. It seemed dry and thus I sprayed it with plastic primer.
Problem was, the resin continued to sweat through the primer and the primer never dried. I couldn't bring myself to throw it out and stored it. Recently, I rediscovered it but, years later, the primer is still a little wet.
Is there a way to rehabilitate this resin piece?
