Can you mix a regular wax and fluoro wax when waxing your skis?

Yes, but why would you? If a low fluoro wax is needed ... then use a low fuoro ... which is less expensive than mixing a non-fluoro one with a high fluoro one. I use the super expensive one's when racing, keep my race skis "prepped" with a high quality non-fluoro wax and only use the fluoro for a race. For my recreational skis they just have a quality non-fluoro wax on them.
