Mike, how are you applying the leather dye? I am interested in doing some testing with dye patina. I actually e-bay'd some burgundy PA's that I thought would be my "test" shoes but after stripping all the caked on wax, I conditioned and polished and they looked too nice to experiment on. I'm wondering, specifically, if you are thining the dye with anything (solvent, spirits, etc.)? Then, how do you go about the gradient blending of colors with the dye?
