Has anyone ever seen any kind of covers that you can cover your front and rear windows to keep from having to scrape ice off of.I made something for the front but in the wind it does not stay down well.Someone told me they thought they saw something made with magnet strips built into the material to hold them down.I already scratched this windshield on my Jetta alittle and I hate scraping ice anyway and I dont like those sprays to melt the ice .Any suggestions....
