Attached is a photo that shows the extreme extent to which the manky old goatskin A-2 that I recently bought on Ebay has faded. I would like to treat it to give it some moisture and darken the faded areas up a bit. Based on what I have read (Thank you VLJ Forum!), I am thinking that Renapur would be a good product. It is expensive though; should I just use vaseline? Or, will I just muck it up and would I be better off leaving it be?
