I have a gunstock with a couple of small dents that can't be lifted using the old hot iron and damp cloth trick. Apparently, there are broken fibers. One dent is round, about the diameter of a pencil lead, and deep. the other is about 1/8" long and 1/16" wide. Is there a filler I can use to level them, or would they have to be sanded out? I'm hoping there's a filler as it
is an oil finish stock and the dents could be easily refinished.
