I use the formbys sealer. Never had an issue with it but I do apolitically it with a make up brush to get it in all the books and crannies.Ok, a question for you guys.. when you disassemble and "seal" a new gun with a wood stock, what do you use to seal it? An oil, a varnish, or what? I just bought a Tikka T3x Hunter with a wood stock and thought I would do this. Thanks.
