Ram 2500 Body Protection

So I bought this roughly 3 years ago to actually help protect from rock chips on my windshield because my job includes following behind semi trucks with oversized loads. Reason for title is because of the install. I took it to an "authorized" installer in Austin Texas 4wp but did not buy it from them and they did a decent job but left gaps and didn't follow instructions completely. Basically if I were to buy this again I'd install it myself even though I know it'd be a pain doing it by myself mainly. As far as the actual product goes it did help reduce SOME chips mainly the ones that cause cross windshield cracks BUT I know from having some major rocks/bolts/whatever hitting it its definitely saved my windshield from a lot of other cracks. Would buy again but wouldn't let anyone else install it.
