when I got to where I was going, the rain was still going strong. I was backing up and the rear camera was hit by so much rain that everything was basically a blur. I had to reverse the old fashion way... looking at the mirror and turning my neck around.

is there any coating or polish that I can safely apply to the rear camera so it can see even in super heavy rain? (stuff like Rain-X or something safer or more effective?)
Thanks!
