My 2022 C8 3LT has beige competition seats with bolsters in Napa leather. It is hard getting in my car without my butt resting on the one when getting in and out of the car. As a result, I have a few creases in the leather. I read that I should use a wet terry cloth rag and apply heat with a hair dryer which I tried to no avail. Perhaps , I need to use a heat gun that has more heat? Any suggestions/ideas would be greatly appreciated.
