I am in the process of restoring a big set of chalked mule deer antlers. I chose to use water-based wood filler to smooth on the whole rack to fill in all the cracks which turned out great. Now here is my dilemma. I want to use tube oil paints thinned with lacquer thinner instead of acrylics this time. The problem I see and cannot figure out is that I need to seal the antler because the lacquer thinner will destroy the water based wood filler. I am having troubles finding a product that will seal the antlers and create a barrier between the lacquer thinner and the repaired Wood filled antler. Any insight on how to go about this would be greatly appreciated.
