Other top-rated dry Pinewood Derby lube includes DuPont Dry White Teflon. This is a fine, non-staining formula often used when local rules prohibit the use of graphite. The purpose of adding lubricant is to reduce friction and add speed. The axle lube kit featured here allows you to burnish your axles with graphite, filling any small scratches in the metal and leaving behind a thin, slick film. For ultimate speed, check out DuPont's pure Krytox®. If allowed by the local rules, this is the best lubricant available.
