I can't speak to the waterproofing properties of this wax since I only bought it for aesthetic reasons. I wanted to wax an old pair of black jeans to get a leather-like finish. It definitely worked for that - it gave my jeans a slight sheen and smoother look that has held up well. However, the bar is quite small (significantly smaller than I expected, anyway) and doesn't go far - I used all but a small sliver on one pair of pants and was definitely hoping to get multiple projects out of it.
