I used this on a denim jacket.
I had an untreated Levis denim jacket that I decided I wanted to turn into a knock around jacket. I looked at Barbour and Otter Wax. They were more expensive and seemed to have put that money all into marketing and brand recognition. I went off label on the directions a little. I melted it in an old pan and used a brush to spread it, a heat gun to soak it in, and sponge to soak up any extra. I threw it inside out and let it run a full dryer cycle on high. It's definitely waterproof now. It's also thornproof and takes abuse well. It is heavier now, but didn't change the color a ton. It is still flexible and comfortable. It took three bars for the whole jacket, 2XL tall. It doesn't have an unpleasant smell, mainly beeswax notes. I haven't had any wax rub off on anything else. I got it very dirty and dusty. All it took was a few dunks in cold water to clean it up. I believe this will last the rest of my life now. I may do another application. I'd like it to be a little stiffer.
