I want to repair some severe dents and gouges on a well abused type 99 stock. Is there a recipe for a stock filler made of sawdust or sanding dust that will take stain reasonably well that can be used as a filler vs, the plastics that are available on the shelf. The only advantage is the stock has not been cut so there is not much to lose on collect-ability. I have repaired the cracked wrist and pinned and doweled behind the recoil lug and action area with methods carried over from the site that turned out well enough for me to doctor the appearance to be completely satisfied. Thanks for the help.
