SWIX LF8X Red Wax is a standby in warmer regions with high water content snow, like the Pacific Northwest and California. LF denotes "low fluoro" which means fluorocarbon compounds have been added for improved performance, especially in wetter snow. The new "X" series waxes are a further development of the trusted LF waxes that have dominated the industry for years. For best results, apply with an iron, scrape and brush.
