I bought my Combat Touring Boots in May, 1998. I got a tub of Aquaseal at the same time. I put 3 coats of Aquaseal on my new boots, and then have put on a new coat every year or two since. My boots now have I don't know how many miles on them, but well over 100K and my feet have never gotten wet in them.
I'm now on my second jar. First one lasted quite a long time. Several seasonal applications to my combat tour boots and roper gloves. Works well at both waterproofing and feeding my leather. I decided to try it on my Corbin saddle and it worked well. Saddle isn't slick at all and appears to be newer and not dried out as it was before treatment. I would recommend. (Posted on 5/25/12)
