Well I got to thinking after using some of this stuff on a deck for the in-laws.
I bet it would work on a gunstock.
Basically it is like a rino-liner for wood. It offers texture and protection as well as they can make it any color you want so when i get some money together I think my 10-22 stock is in trouble. Just need to see if they sell it in something smaller than the 2 gallon package
Just thought you guys might be interested in it
