Review on T-Rex Rear Bumper Guard: Ultimate Protector for Cars by Diztymewntu Sacra

Have had bumper protectors for a while. I only took it off at the car wash and put it back on when the car was dry. I took my car to the car wash today and found this. Black dots anywhere on the bumper where the tread was and air bubbles of distorted color at each corner or bumper. Black dots do not disappear, it seems that air bubbles also remain.
