Ya know, I guess it's neat to try to do things like this beeswax/turpentine mix for a olde timey/historical manner. But the fact is we spend good money for guns and wood today and there are several excellent gun finishes available that are easy to use and proven.
I wouldn't smear that kind of glop on anything I've just spent hours refinishing let alone something I've spent weeks/months building.
I've seen the results of the guns done on that "other forum" and while the guy's recieve kudos form the folks there for doing such fine work in an old manner,, several of them end up over here months later seeking advise to get a good finish.
Sorry, but if someone has used this stuff several times on smaller less expensive projects, then maybe they'll get good results,, but too me it just doesn't make sense to "experiment" on a good guns finish.
Heck you can find Birchwood Casey Tru-Oil at just about any hardware store for $4-5 and get a great-proven gun finish.
