Thanks for the tip ikeepitcold!I use Montana Pitch Blend. I have Tibets too and it works great.
Obenauf's it is... Just used up my last big jug of it. I use saddle soap to clean my boots then oil with Obenauf's.I use Obenauf's on my Tibets
I have been using the spray silicon on both pair of my tibets, works great , just make sure they are clean and dry , I used Montana pitch blend on a pair of Kenetrek mtn ext and it softened the leather to a point that it ruined the boots so I haven't tried it since.I've used Kenetrek's and Snow Seal, both with good results. Put it on and leave the boots in the sun. Soaks it right up. The soles wear out before the leather does.
