Rain Repellent will dramatically improve your wet weather flying, riding or driving visibility, whether in rain, sleet or snow. Rain Repellent is a hydrophobic coating technology that forms a chemical bond and causes the raindrops to bead up and blow away from the windshield. Rain on untreated windshields form sheets and streams of water that cause distorted vision, especially at approach speeds for aircraft and highway speeds on motorcycles. Rain Repellent's innovative technology is designed especially for plastic Acrylic and Lexan windshields, and has no alcohol which can harm plastic. It is safe to use on glass windshields also, for cars, RV's, boats and trucks. It can be applied on painted surfaces, and aids in easy removal of salt, ice, frost, insects and mud. Apply to the exterior of the plastic or glass windshield surface, and reapply as necessary. One application can last weeks, depending on rain volume and use of wipers. And since none of our motorcycles have windshield wipers, we know that means it will last longer!
