I want to try a method in which I glaze over monochromatic, heavily impastoed underpainting in oil. My experiment looks promising, but the underpainting is taking an unacceptably long time to dry, even though it's heavily laced with Galkyd Gel. After a month, the thicker areas are still soft to the touch. So, two questions:
1. Does anyone have any information about archival problems with using oil-based glazing media on top of acrylic paint? It seems like it would be a bad idea to put a petrochemical solvent on a flexible acrylic polymer, but I've also seen plastic gasoline cans, so I don't know.
2. Can anyone help me put my finger on why liquid acrylic medium just doesn't freaking look like an oil glaze, and what to do about it? I'm thinking of a 50/50 mix of gloss and matt medium, and slapping a coat of it on the underpainting before going on top with an overpainting of acrylic paint and the same medium to try and get some, I dunno, some atmosphere in there.
