Maybe a little off topic on a car forum but I figure they way we all analyze our auto fluids perhaps there are some people on here knowledgable on this topic. Just picked up two new pairs of boots and thinking about the best product to use to keep them Michigan winter ready. 1. Danner Recon. This are smooth, black full grain leather. In the past I have used Obenaufs LP extensively. Unfortunately this has seemed to over soften the leather although it's be a durable and highly effective water proofer. Sno-seal has also worked very well but seemed to cake on the surface and leave a lot of white residue even after heating. Nikwax leather wax has worked well but offers very poor durability. Surely there must be a better compromise. Currently looking at huberts boot grease and picar's but no experience woth either yet. 2. Matterhorn CV3494. These are insulated and goretex like the danners above but feather rough out full grain leather. I have limited experience here. Nikwax spray has proven largely ineffective in the past, as has silicone. 303 fabric guard has offered mild success. Any other suggestions? Obviously they won't bear water as much as smooth leather but I would like to minimize the amount of water absorbed and prevent staining.
