I purchased a bottle of "Mr. Resin" a primer produced for resin kits sold under the Gunze-Sanyo brand. It brushes on okay but it would be easier if it were airbrushed on. It is thicker than GS's "Mr. Surfacer" primer for plastic. Does anyone know if Mr. Resin can be airbrushed on and if so, what is used to thin it? I've tried paint thinner, turpentine, alcohol, water, etc, but no joy. Testor's liquid glue seems to work as a thinner, but it's rather messy and I suspect dangerous, it evaporates too fast causing the solution to clog up and I'd rather not shoot it through my airbrush.
TIA
