I am going to email Xpel.
I wouldn’t bother with contacting Xpel directly, they just make the product and sell it in rolls to installers. The authorized installers have computer controlled patterns they cut on site but that’s for the common stuff. Entire front end of an Audi Q5? Yep, point-click-done. Anything non-standard like what you’re looking for is done free hand on the vehicle.
Xpel is pretty good stuff. It has self-healing properties that allow minor scratches and nicks to disappear when exposed to the sun. Bigger rocks that cut all the way through will cause damage that cant cure itself though. My daily driver caught a rock about the size of a marble while going 85 mph. It made a 1/8” nick in the Xpel but left no damage on the vehicle.
