I've got a 2019 Grand Sport convertible, I had it done in SunTek Ultra in April 2018. The dealer was authorized for SunTek, Xpel and 3M. I chose SunTek Ultra because it offered the same thickness, self heat-healing properties, and 10 year warranty (including discolouration) as Xpel for a little less $$$. SunTek Ultra also offered a choice of gloss or matte finish at the time. My installer opinion was SunTek Ultra and Xpel were so close he couldn't say one was better than the other. I'm happy with my choice, I don't think you'll go wrong with either. If I were to do it again, I would pay the extra money and go with a custom hand cut rather than the computer cut pieces because the hand cut truly does a complete wrap under hood, doors, trunk, wheel wells, etc.. Good luck.
