Well, I'm not really concerned about completely waterproofing it, so long as it holds its shape and the dye doesn't run.
What is Resolene like to work with? I take it that if you can add conditioners afterward, it must leave the surface permeable rather than forming a solid surface film. Does it tend to stiffen the leather? How does it compare to Leather Sheen?
Should've mentioned before: I currently have Sof Sole Leather Lube, Wright leather conditioner with mink oil, and some old Kiwi Wet-Pruf that's dried up to the point that it has a texture like beeswax. Would any of these be useful, or should I get Snow Proof instead? I also have a block of pure beeswax.
