Rainy Day Ride

[Vegas Street Rider]

Just got back from a ride in the rain, in Vegas no less. Stayed toasty dry with my Frog Togs pants and pull-over boots and a yellow slicker over my riding jacket for visibility. My only real issue other than the usual stupid drivers was with good visibilty through my shield. It was not so much fogging up as my helmet has great pass through vents, but with actual drops on the shield, making it tough to see at times.

Any suggestions of what product you all use to keep the raindrops from accumulating on the shield. Something like Rain Ex but for plexi-glass.
