Renaissance Wax

[66Park]

If you clean a gun and apply a light coat of any descent gun oil and the gun is rusted in only a month...... I would have to say that you are storing the guns in a very damp and humid environment. If that's the case, oil or wax won't solve the problem, but a dehumidifier or golden rid in the safe might.
Just saying..........

It wasn't just a month, and it was thirty years ago.

Microcrystalin waxes such as Renaissance, are an industrial standard for museum conservators for a wide range of items, including firearms. Waxes are ideal for metal surfaces as a hard protective barrier to moisture and acids (fingerprints). As a museum curator, I've used either Johnson's (high in carnuba) or Renaissance for years with no negative results.

Smells good too

As I said, I use Johnson's, and have never had an instance of a waxed gun rusting. But where I live, the relative humidity is low most of the time. Steel doesn't rust much until the relative humidity exceeds 50%.

ren wax and options on rust prevention

I use ren wax on my "collector" guns that dont get shot and
after having my shooter guns get a little surface rust since humidity was present after I handled them. I now run a dehumidifier in the room where the shooter guns are (humidity is 40 or lower now) and I spray on them Brownell Rust Preventive no 2 and rust has not reappeared. The brownells RP 2
displaces moisture and remains on the surface for a long time.

Since I am NOT a Brownell's employee or affiliate I can't swear to this, BUT I do believe that the Brownell's RP-2 is nothing more than private labeled RIG #2 Oil which as some here may know is my all time FAVORITE gun juice! I have even asked Frank Brownell personally and he said "no comment". Either product is great though.........
