SOFT99 Fusso Coat F7 is a durable synthetic sealant with class-leading hydrophobic (water-hating) properties, and makes use of cutting edge TSI (Top Shield Impermeable) and WARP (Wipe Assistance Radical Power) technologies to ensure optimal performance and ease of use. Comprising a fluorine polymer (resinous polytetrafluoroethylene, or PTFE for short) suspended in a solvent-based carrier solution, it dries and cures to form a hard protective film that is extremely hydrophobic. As a result, rainfall and rinse water bead up and roll off very quickly. This extreme beading not only looks good, but also tends to pick up and carry away fresh contaminants, which makes routine washing easier and safer. In addition to these benefits, SOFT99 Fusso Coat F7 also produces a sharp wet-looking shine and provides excellent protection against bird droppings, bug splatter, road salt and UV radiation for up to seven months per application, even on daily drivers. These properties make it an excellent choice for standalone use, and ideal for use as a basecoat beneath the less durable but more hydrophobic or aesthetically pleasing sealants and waxes in the SOFT99 range (e.g. Water Block Wax for stronger water beading, and King of Gloss or Mirror Shine Wax for more wetness and gloss).
