PropGlide® is a foul-release coating system that, when applied to propellers and stern drives, increases fuel efficiency and performance of any vessel.This high-gloss coating keeps the propellers clean from marine growth for extended periods, reducing the resistance caused by fouling on the propeller and stern drives.This way, higher RPM and boat speeds are achieved, providing greater efficiency to the engine.It is not an antifouling for propellers, but a coating without the release of harmful substances.Easy to apply for both DIY and professionals.
