I have always used Xpel paint protection film (PPF) on my cars for the front bumper and partial hood. My GT-R has 3M stuff because 12 years ago, Xpel was not as common. The good side is that bugs in summer, rock chips all year round and salt chips in winter do not damage the front of the car, especially highway driving.
The Xpel PPF is also self healing, which has been good over the years. The one down side is that it increases the cost of repair. Having a bumper to bumper accident that requires work on the bumper adds an extra cost to the repair. The film need to be removed and new one reapplied and many times insurance will not cover the extra costs.
A buddy of mine owned the only Xpel certified shop in town and he recently sold it and moved, so I decided to try my DIY skills. The two areas of concern for me were the top of the rear bumper on which I saw a scuff mark from loading/removing my bike into the trunk and the rear rocker panels for which Tesla is offering a DIY kit on their accessory site.
