First off has anyone ever used this? Is it worth it? How long does it last?

I am curious about it but not ready to do it. What I am looking for is just a sheet of the material so I can cut it and apply it where I wish. Products such as 3m Clear Mask and XPEL are custom cut to your vehicle and installed by a professional.

Does anyone know of a company that sells a product like this that I can use to protect my car in certain places? My license plate holder rubs against my front bumper due to the way it is factory installed. The visor deflector above my moon roof also causes some issues among other things.

Help as always is greatly appreciated!
