Our specially formulated glass cleaner and rain repellent in one will leave your glass with an excellent streak free finish and enhanced wet weather visibility. It's very easy to use, simply spray and wipe until it disappears with no specific preparation of the glass needed before hand and will only leave behind our water beading technology. Rain water will simply bead up and roll off the glass. This protective layer will also make it easier to remove snow, ice, and road grime. Spray onto the exterior glass and buff off, it's that simple. This will allow greater amounts of water to be removed from your windscreen when using your wipers making visibility in wet weather easier. This product may cause fogging if used on interior glass.
