Sorry for adding to all the redundant Brooks posts, but I am looking to break in my new X-mas B17, and the one I got (via ebay) didn't come with Proofide. I know the company touts it as the only saddle conditioner one should use on their saddles, small wonder as you have to buy it from them. I, on the other hand, wish to either make or buy a very similar product to use on my saddle so I am not bound to buying Proofide. Does anyone have a clue as to the ingredients in Proofide? Searches have come up negative. I would be especially interested in a list of ingredients in order of most-first. I am also interested in names of products very similar to Proofide. I don't need advice on other methods of breaking my saddle in, I am doing it the traditional way. And no, motor oil isn't a saddle conditioner...
Thanks in advance!
