We use a bra on the current Bus and after I peeled the Diamond Shield off the last one, I used one on our 08 Bus. We put it on for travel and off for stops more than a night or two and we CLEAN IT FRONT AND BACK. I sold the 08 with 75,000 miles and we have 23,000 on the 13. I wouldn't drive without it and the fronts looked brand new after using them. You will get an occasional chip under them but these can be fixed whereas the Diamond Shield cannot. Lots of gravel and dirt as we're in Alaska five summers out of the last 8 years. We get our bra's from http://www.coastlinervandoffroad.com/. They'll custom make one for you while you wait (with an appointment) in their parking lot if they don't have your pattern.
