I collect WWII as well as Boston Police Guns ( http://www.bpdguns.com is my website for that)
I have used oil for protecting the metal on the guns but now there are a variety of treatments from Renaissance wax to spray products.
I am trying to decide what to use, I currently have a can each of Barricade and Kleen Bore Rust Guardit
Does anyone have experience with any of these?
