Propspeed helps prevent fouling of propellers, shafts, struts and more to give your running gear a long-lasting, ultra-smooth surface.The Propspeed SystemIn addition to Propprep, the Propspeed System includes four additional components: Propstrip, Propclean, Etching Primer and Propspeed Clear Coat.
