To celebrate winter, I'm in Southern Cal., I pulled down the stored hardtop from the hoist stored in the garage ceiling. Last time I had the hardtop on was about 5 years ago and I wanted to enjoy the altered aesthetic. I noted some bubbles in the liner, drove Z8 a few miles and by the return the liner was sitting on my head. The liner was not salvageable and I had it replaced with similar material. Note to those with a hardtop lift, the garage attic gets hot.
