I know this is an old post, but I hope someone can help me. I'm working with a Black Stone Oil Leather from Tandy and no matter how much I clean and rub it, black dye keeps coming off on my rags. Will Resolene help to stop dye transfer? Any suggestions? I know one of the first suggestions is to never buy Stone Oil Leather from Tandy's again. I usually get Utility Leather but black has been very hard to find in a 4+ oz. and I made the mistake of buying this.
