Your dealer recommended it!?!? Go back and give them a slap from me!

Do not wrap your car with anything. Do not put stickers on the body if you do a rally. You take them off and your paint will go along with it. You have to sign a waiver if you get matte paint and the factory rock chip protection film as once you remove it, you're game over. I've seen a local aventador that screw his entire Nero nem matte finish by removing the protective film he got after he bought the car.

Pretty much you'll have to live with any marks. Even the factory matte paint from Mercedes (I have experience with the GLA45 AMG) suffers from this. My local dealer installed a half clear bra and the guy who bought it wanted a full so no line across the hood. They removed it and the the paint went bye bye. They had to order him a new car from another dealer.

It sucks, but goes with the territory. BMW Frozen M3's weren't allowed to have any film installed at all by any dealer as well.
