I had a simple idea about keeping from scraping the bottom/front of my winglets on curbs. How about applying some xpel or 3m clear headlight/paint protection film to the winglets, folded up to cover the front edge as well? I know xpel sells different widths by the ft. http://www.xpel.com/products/bulk.asp Of course you still need to watch out for high curbs but I seem to be able to deal with these but instead seem to scrape the bottom of the winglets on lower curbs and incline/dipped roadway entries. I might give it a try when I have some free time. Has anyone tried this?
