I have a very fine miniature, quite rare, in resin which I am trying to prime in gesso. I have washed it three times with water and dish soap and twice with simple green and dish soap, yet I cannot remove the mold release, because each time my primer incurs the separation effect and beads up instead of adhering properly.
I have primed resin miniatures in gesso many times efore and there's no reason it shouldn't work this time. The resin does not appear to be sweating - it is very slightly waxy to the touch, but not damp or sticky or anything else.
For a variety of reasons I can't use aerosol primers, so please, no suggestions of "just go buy car primer, duh." or the like. I'm no good with those can anyway and would just glop it.
Is there anything else I could use to try and wash off the release agent or aid in adhesion?
