I have learned to ignore my OCD on this. Right now in New England the bugs have come out to play. I came home last night and the windshields were covered in bug juice. When I have time today I'll make the attempt or just let it sit out in the rain to soften the worst of it before I have to tackle it.

Thank dawg for beer...

What's your mileage? Who cares. Is it practical? See #1. What happens when it rains? You get wet.
