Exactly. That's a difficult material to get paint to stick to. Not only do most flex agents work like shit, but the textured finish is going to have to be sanded off and it will most likely leave an uneven surface. They're not backing their work for a reason. Not to mention, it's a new car, and you're going to run the risk of paint not matching.

If I were you, I'd just leave well enough alone on this.
