303 Protectant will slow and / or stop life jacket fade caused by hours in the sun. It is genuine sunscreen for your equipment! Spray it on life jackets, helmets, rafts, the dashboard of your car or your hot tub cover. Regular use of 303 provides the ultimate in preventing UV color fade. 303 does NOT contain silicone oils, waxes, glycerin or petroleum distillates. It leaves a like-new, non oily, anti static finish that will not attract dust. Also helps to renew the gel coat on fiberglass surfaces. The larger size containers are more economical and can be used in the same vat of water as Sink The Stink (sold separately).
