Unfortunately, to keep it from fading you will need to apply something to it. I haven't noticed my wipers ever getting far enough down on the windshield to hit the cowling. If you do go with a coating, I'd recommend 303. It does a great job of protecting plastics from UV.anyone have a suggestion on what to use to keep it from fading? i'm reluctant to put anything on it because I don't want it to get on my wipers and spread to my windshield ( happened before.. )
