Sailors create a super-slick racing finish with this paint.FW-21 Slick Coat Racing Paint is an ultra-thin, super-slick, low-friction film for boat bottoms. It is the ideal racing finish for fresh water or cold salt-water boats. FW-21 combines copper powder, Moly-Disulfide and PTFE to produce a super-slick paint film that reduces surface friction, allowing the hull to slide through the water. FW-21 is recommended for use on fiber-glass, wood and properly primed steel boats. It is easy to apply and dries in 15 minutes. Color changes upon immersion.Specifications Type: Thin-film Solid LubricantRecommended Usage: Freshwater and cold saltwaterNumber of Coats Recommended: 3Coverage: 80 sq.ft./qt. kitDrying Time: To overcoat: 5-20min.; To launch: 30-120min.
