I used to use suntek carbon and switched to pana flex. I know they are not an apples to apples comparison because the suntek is a carbon film and pana flex is ceramic, but I have absolutely loved the pana flex. Super easy to shrink doesn't crease easy. I have suntek on my personal vehicle and it has done well no complaints. My wife's personal car is done in pana flex and you can tell the difference. I was buying the suntek carbon but got the same price I can get ceramic technology from pana flex. I have had zero issues in the 3 years I have used pana flex failing on the vehicle! Ralph has been great. I had one issue with pana flex being on back order for two weeks. Other than that great product
