I just finished inletting a stock for a Nitro Special. I made the mistake of not doing the tangs separately and ended up with a small gap on the front of both sides of the upper tang. I saved some of the fine file dust. I also coated the exposed bearing surfaces of the stock with Superglue. Is there any way to mix this dust with epoxy and fill in the gaps? Any other methods? This is a hunting gun that will get wet repeatedly.
