I'm sitting in my motel room outside Nashville tonight after riding 500 miles in pouring rain. My Bridgestones worked great on the pavement but what was really a pain was not being able to see through all the raindrops on my face shield. I've always heard that rain-x is not good on the shield, and I've tried lemon pledge, still raindrops cling to it even though I try to blow them off with my windscreen vent open. It doesn't fog if I leave it cracked a bit. My helmet is an HJC CL-14 full face. What will let these raindrops slide off? I'm ready to put rain-x on even though it might not work. Thanks.
