We had 3M on the front of our 2013 Volt and it did a great job protecting it from rock chips on the dark blue paint. For 3+ years. So when we got the 228i and a new Volt ('17), I had a well regarded local installer put it on the front, partial hood, outside mirrors, etc.. It was about $650 per vehicle out here on the central coast of CA.
