Shotgunlover,
Brownell's "GunsmithKinks" Books had some information on using thinned Acuraglass (2 part epoxy) as a finish & there were apparently some people doing this 30 years ago so I don't know why this couldn't be used as a grain filler along with a more traditional looking topcoat.
I've often wondered if something like this wouldn't work for those nice looking blanks that are really too "soft" to make a good quality gunstock (I'm talking about surface hardness rather than structural consideration). I would think the fine detail sanding around drop points & such would be an issue with anything filled with 2 part epoxy.
I do know that several custom gunsmith are using Daly's ProFin & or SeaFin. These products are not 2 part epoxies but are promoted as penetrating finishes that "harden the wood up to 40%".
Unfortunately, really good stock blanks aren't as common as they used to be & some way of improving marginal blanks would be a plus as well as the water resisting qualities.
