Finally reading over my paperwork. Looks like the dealer threw in the Mopar MasterShield treatment. Some kind of paint protector, interior protector, etc. etc, etc. What is this? Is it even worth my time to take it in for the treatment? Or is this the old "underbody treatment" with a new fancy name. In other words, did they just throw in something that costs them $10 and they charge $500 for?
