I have been trying to Rust blue my Model 10 s&w and have been having some problems. I Am using Laurel Mountain Forge bluing solution. I stripped what was left of the bluing and degreased with acetone. I put the solution on and wait until the parts get a even coat of red rust and then I boil in distilled water and card off with a carding brush. I do this until I get a nice looking blue then I coat it with Boiled linseed oil and let that cure. The problem I am having is after they step the blue looks great but I can rub it off with little pressure. There must be something I am doing wrong, because I did this whole process twice and the same thing happened. Help would be greatly appreciated.
