Hi John!
[Urrrrrrrrrgh! Pulling things more firmly back on-topic, thanks to your Obenauf's post...

You're absolutely correct; Obenauf's enjoys a fine reputation here'bouts for protecting leather and leather saddles and is also endorsed and sold by Rivendell for that very use. For those interested in giving it a try, here's the link to Obenauf's for the paste:
https://www.obenaufs.com/index.php?route=product/product&path=20&product_id=30Also popular with some is Sno-Seal (
http://www.atsko.com/products/waterproofing/sno-seal.html ). I prefer this for my Danner Gore-Tex lined boots, since it doesn't soak through like oil to contaminate the Gore-Tex (avoids causing leaks through altered surface tension at the liner) yet feeds the leather and protects it from rain/wet and snow. I usually do 1-2 boot treatments a year and it hasn't stretched my Mountain Light IIs (
http://www.danner.com/boots/mountain-lighttm-ii-mens-womens-hiking-boots.html ) in all the time I've used them. It holds up remarkably well against ice scuffs on crusty snow, and nicely restores the appearance afterwards. I prefer to warm the boots to room temperature, apply generously, and then apply heat from a hair dryer at arm's length as I massage the Sno-Seal into the leather with my fingers. I heat the Sno-Seal
just enough to keep it shiny; if the gloss flattens out, it is too hot and needs either less heat or more Sno-Seal. the idea is to warm it and the leather just enough for the Sno-Seal to penetrate but never so much heat as to damage the leather. When the leather appears to have soaked up its fill, I let the Sno-Seal cool and become gelid before polishing off the excess. Friends who have used this method to Sno-Seal their Brooks saddles have been happy.
When I Proofide my Brooks saddles, it is always at room temperature and I place them near a sunny window After to accomplish the same purpose to help it penetrate the surface.
I've known several people to use mink oil, all with bad results. I'm not sure what caused the problem, but the leather seemed unusually dry afterward. It had the same effect on my father's favorite hiking boots, so we have forsworn it; there's probably others who have had great success.
'Never heard a single bad word said about Obenauf's results on Brooks saddles.
I've always thought there is something wonderful in the success people have had with different leather treatments on Brooks saddles. Obviously, no one solution is right for all, and everyone has their favorite. If you ever ride with another Brooks user and run out of conversation, bringing up this topic is fodder for another hour or so of talk.
All the best,
Dan. (...who thinks it either doesn't matter or matters entirely on believing it -- whatever "it" is -- works.
