Windshield install question

[2017EX_imp]

I have used something called "Body Guard" for applications where I want to protect a finish from "clamp marks". It is used on the rocker panels of cars to protect against rocks chipping the paint. It is fairly thick, clear, and self adhesive. You can find it at auto parts stores. A small roll will be about 6 inches wide, maybe 15 feet long. My roll has lasted a long time, cutting off what I need for various projects. Just depends on what you want, as there is nothing wrong with clamping on without a protective layer underneath either.
