So I've made a few helmets with Smooth Cast 320 using the slush-cast method and had good luck priming and painting. However, on one of them, I filled the dent with Bondo and sanded flush. I've sprayed with primer, but the paint won't fully dry in some of the areas around the Bondo where the Smooth Cast was lightly sanded. I've tried 3 different primers, and have cleaned the areas with both alcohol and acetone (at separate times), but the primer will still not fully dry in those areas. It fully dries on the surface of the Bondo, and the areas away from where the Smooth Cast was sanded, but it seems like it's just the surfaces where the Bondo was sanded away from the Smooth Cast that are having the issue. It's not like it's orange peeling, or not bonding to the surface, it's just that it won't fully dry. I'm in California, so I don't think it's a temperature/humidity issue. Has anyone had this problem, and do they know of a solution?
