Getting out of the art. I have 2 Bobcats and a Grey fox left to do. I'm seriously thinking of Using DP on these last 3 mounts to save time and not have to order tanning supplies. How big a difference will it really make on these thin skinned animals? I've never used DP on an animal but have literally mounted a 1000 fish and birds that still look perfect 20 years later. Some Geese I've done had thicker skin than the 3 animals I have left. Never has been a "Real" tan for fish or birds. Is the Dry preserve just rubbed on the flesh side like fish or do I tumble them like birds so both sides of the animal skin get preservative on it?
