I need to put my barreled action in my finished stock. But I want to put some sort of sealant (waterproofing) within the stock cuts. What should I use??
Thanks....advice much appreciated.

I'd use tounge oil.

I've used everything from marine spar varnish, to urethanes, Tru-Oil, tung oil, and thinned epoxy. They all work to a certain degree, but IMO, it's almost impossible to completely waterproof a wooden stock.

Any water thin sealer will work fine.

I do that on a new stock as I finish it, but you can expect to have to do some more inletting before the barrel and action will go back in...

Thank you gentlemen....I went out and bought "tung oil"....will do.
