I don't know what was on my 991tts. I was planning Expel but the Ferrari sales manager said not to use them but to use another company that sells Suntek. He said not because the products were that much different but because the guys at the Sunbusters did better work. So I picked Sunbusters and have been satisfied with the result. They have a machine that knows the patterns for all the cars and cuts them on site. Pretty nice setup. Very clean and the installer was definitely very experienced.
