F4 Glidewax Liquid is a versatile glide wax, making you perfectly prepared just before you hit the slopes. Apply a thin layer over the base surface. Let it dry for approximately 2 minutes. Finish by polishing. When you're done with the season apply F4 on the metal edges before storing your skis or snowboard. This prevents the steel edges from rusting while storing. Universal wax for all temperature ranges Developed for alpine skiing Prevents rust on steel edges Easy application Fluoro-free
