Some of those concoctions go hard in the can. I had a can of Formbys rubbed oil finish, that I bought for a table, that went hard after about a year. I did get my table done, but, the Minwax wipe on poly I used on the gun would have been better. It never went hard in the can.
My walnut gun cabinet and the black walnut speaker stands set I built for my Klipsch Heresy speakers were finished with Watco Danish oil. It was OK indoors. Not sure about using it on a gun. The gun cabinet was replaced with a safe.
Best,
Ted
