FWIW, ever since I slipped & fell into a 12" deep puddle with a Remington one Winter over 30 years ago, and ruined the stock finish because the water entered & expanded the wood via the raw wood under the buttplate. I've removed EVERYTHING from the stocks of "new-to-me" guns that wasn't wood, and laid Tru-oil or thinned epoxy onto the un-finished surface normally hidden when the gun is assembled, until the wood would not accept additional sealer.
I let it dry/cure a few days before re-assembling/shooting/hunting, and have never had a problem since.
