We had a NASTY windstorm last week. Sustained winds of 35mph and gusts up to 50mph that lasted all day. I could hear my car getting absolutely sand-blasted both to and from work. I was hearing pretty good sized pebbles hit my car as I drove through the various sand clouds. Ugh. Finally had time to wash her up today and not a single chip or scratch or anything after I was done! My windshield is starting to get etched, but that is pretty unavoidable out here in the desert, unfortunately. I am very happy with the $$ I spent on that wrap. It is a full body Suntek one. I am using the green Optimum no-rinse and the two bucket method to keep her clean - nothing fancy. Before - yikes! Halfway done: All pretty again!!
