I had a scary commute this morning. It was dark and it was raining. I don't normally ride in the rain if I can avoid it, but having checked the forecasts I decided that I would take the chance of encountering a little bit of rain, rather than endure the pain of having to commute by car.

This morning's rain was no more than a drizzle at best, but it was the scariest ride I've ever had. Combined with the darkness, the visibility was crap, mainly due to the accumulation of water on the outside of my visor.

I literally had to wipe my visor with my glove about every 5 seconds, to maintain semi-decent visibility and I don't remember ever having to visor wipe so frequently when I've ridden in rain before. I even wound my screen down to try to get the air to blast the visor clean but that didn't help much.

So my question is: What product should I use to treat my visor so the water will bead off? You guys that are regular 'riders on the storm' probably have a few tricks up your sleeve for maintaining a safe level of visibility and I'm sure it doesn't involve manual wiping, which I don't regard as safe when it has to be done so frequently.

I'm thinking of the products one uses on a car windscreen (C-Thru, Rainshield, etc.) to make the water bead off. Can one use these products on a perspex visor without damaging it?

Thanks in advance for your suggestions.
