I've used Notwax for several seasons now. It is not a substitute for waxing. I usually mix it in with the hot wax (their Felix Method of use), then top it with notwax. I keep the skis topped with notwax, and have to wax less frequently. Notwax is great in wet (warm) snow. Their is a warning with it (read it carefully) that says it will basically stick on very cold (I can't remember the temp. threshold) snow. I'm a Mid-Atlantic skier, so I feel it's the best stuff I've ever used, but I'm usually on a pretty wet surface. I get great glide, and can procrastinate about waxing with it.
