There any drawback to using Rain-X on our Lexan windshields?
I got into some nasty downpours on our trip around Kenora Ontario a couple of weeks ago and the water just sat on the windshield and wouldn't run off. So you say to yourself why not pull over and wait it out, there was no waiting this one out.
I was 100 miles away from base camp and the sky looked worse over my shoulder.
