Because I'm so cheap I have started making my own wax for my blades. I read a report on wax experements with different waxes. I'm not sure if it was Wayne Goddard or Steve Bloom, but the result was that bee's wax was the most effective at preventing rust.
I found a formula on one of the places I frequent, maybe TheForge, that mixed equal parts of bee's wax, mineral spirits, and linseed oil. The person who posted recomended plain linseed oil but I used boiled, it's what I had on hand, and it works fine. The next batch will have a little less spirits because I would like it a little firmer.
I bought some Cardoba (sp?) wax and plan to add a little to the mix. I bought two different kinds of rust preventave from that guy that has the 1911 semi-auto in the salt water at the Blade Show but this mix works better for me here in rusty South Florida.
Just what works for me, Lynn
