The original tonneau cover's used to leave their mark on the sticker's also. I had my HZ for not quite three year's and the sticker's were becoming wrinkled and just starting to get grit under them. There was not a lot I could do about it. Being my first ute I also learnt a valuable lesson in removing the cover after rain, or washing the vehicle. If you don't do this all the condensation get's into the paint under the the edge of the cover and it blister's.
