Zardoz Base Boost is a teflon coating that’s wiped on to the ski base & works very well, especially in wet snow. It used either to supplement the wax for additional durability &/or speed, or if there’s no time to hot wax. It’s also excellent at preventing edge rust. Combine this with the fact that it doesn’t harm the bases, it’s cheap & either the wipes or the ‘pocket puck’ easily fit in a jacket pocket for easy on slope use means every skier/tuner should have some.
