The other day I dug out a pair of boots that had been sitting in my hot garage for about 20 years. They were a pair of US Military issue black boots. Where I live, the garage often heats up to 100 degrees or more in the summer. I normally do not store prep in it because of the heat. The last time I used the boots I had coated them with Sno-seal before putting them away.
Surprisingly the boots were in good serviceable condition. I cleaned them up tried them on and found that they still fit fine. After renewing the coat of Sno-seal, I set them in the sun to get warm so that the Sno-seal would penetrate well. The boots were then placed back in storage but in a cooler place.
Sno-seal is a product that a shoemaker told me about 30 or more years ago. Sno-seal the original is the one I use. It is made with bees wax. There is a new version for sale but I am still using the original. Sno-seal claims in its adds that it
- Penetrates into the grain providing maximum waterproofing.
- Lubricates and conditions leather without softening.
- Preserves and lengthens the life of leather.
- Does not interfere with the natural breathability of leather.
After using it all these years, I believe them. It has worked well for me and I have no qualms about recommending it.
