Has anyone tried any kind of anti-rust coating (OTHER THAN OIL) on your non stainless knives?  If so what and how is it applied?

renaissance wax, various gun compounds, intentional patination, etc...

The higher polish on the finish, the more resistance to rust starting, then wax/oil regularly 

I like to use horseradish to patina blade.  Seems to not rust so far.

Otto if you would, describe the process a little, unless you are yanking my chain, I am interested.

Variation on the mustard patina, which you should be able to find in a search.  Think of how the old high carbon steel cooking knives blades looked after long use.

Yeah I found some info on forced Patina.  I will give it a try...Thanks

The horseradish patina is easy.  I do it on some of the knifes I make.   You polish the steel up a bit then you dab the horseradish on the bare steel.  Leave it on for 10 minutes wash it off with water.  Do this a few times.  I usually do it 4 to 5 times for a knife. It will give a dark patina like an old carbon steel kitchen knife. I read about it in the 50$ knife shop book.  He also said he uses mustard.  I have not tried the mustard myself though.  

I use car wax.

I know a couple of guys who use car wax on their carry pistols to prevent rust.  I actually thought of trying it, now I may...Thanks

I usually use renessaince wax on everything from tip to butt. Always a nice luster then. If it is going to a new home I use either beeswax and give them a small piece so they can clean and wax it themselves. 

I like Beeswax, I use it in leather crafting and in making bowstrings.  So you just rub in on and buff it in I guess.  No heating?
