Backing Big Cat on the moleskin issue. I was fortunate my tinter told me up front he was going to have to use moleskin in order to not have scratches occur.. The mustang door materials will destroy the tint fairly quickly. Be sure to confront your tint installer about this and do not accept any story about how great his tint is, how durable it will be, and how scratch resistant the product has been on every other car. The mustang inner rubber strip is hard as a rock and it's guaranteed to scratch.
