This painting stuff is all new to me. I've done some research and see the paint comes in air dry and oven dry. Sounds as though the oven dry is more durable but the air dry gets pretty good marks as well. Here's my quandry: I've got a very rough Mannlicher Schoeneur with deep pitting. This thing is too rough with far too many pits to fill with weld, finish and re-blue. I was wondering if this might be a good candidate for painting. If so, what is used as a filler for the pits? Thanks, Dan
