My wife and I picked up our Model X on Wednesday. We bought the 7 seat version which makes the view out the back window - using the rear view mirror - very limited. Consequently my wife decided to use the backup camera as a high tech alternative. It really works very well when it's not raining. Well we live in the Seattle area and as everyone knows it rains here a lot...like 300 days a year. The water droplets completely obscure the camera lens and the result is an unusable image. I guess they designed the car in sunny CA and din;t check it in the rain..or something. Anyway I digress. I was thinking of using Rain-X for Plastic, which apparently is not as good as the standard Rain-X which is designed for use on glass only. Any suggestions on how to deal with this issue.
