Raincoat® Advanced Water Repellent Coating - 5 Pack
Easy to apply and long lasting, Raincoat has a special wax blend that is suspended in a volatile oil.  These waxes are hydrophobic, that is, they 'hate' water. They repel water by beading up the drops.  Because those beads of water have less contact with your plastic optics, the larger ones run off with gravity or the wind.  The remaining water will appear as smaller and more rounded droplets rather than a smear that distorts your vision.  By repelling the water, the trapped dirt and salts stay off your lenses or shields. So you will not need to clean them as often. Aso, it has been reported that ice and snow find it difficult to stick to plastic surfaces coated with Raincoat Advanced Water Repellent Coating.
