2019 Mercedes-Benz GLA45 AMG - Should I Rustproof?

I just bought a new 2019 mercedes GLA hatchback and i would like to know if I should have my car rustproofed and if so what type of rustproofing should I get?

I wouldn’t waste your money on it. The rustproofing that is done in the factory is usually sufficient. The stuff the dealership offers is just an extra profit center for them with an insanely marked up price

None what so ever because it is a waste of money . Also sometimes whoever does it can plug up the factory drain holes that keep your vehicle from rusting inside out.
