The front end cover can either be Diamond or 3M. Two different products that require different methods to remove. My 35F Vista has diamond on it and now has mold growing in the glue. It looks like little brown spots and will not clean off. This is a common problem in Florida. RV world in Fort Myers quotes between 800 and 1K to remove the mask. I would be very careful about putting a bra on top of the clear protectant as it might hold moisture and accelerate the mold growth. For those that have the growth and want to remove it there are youtube videos that show how and has links to the products you need to use for safe nonmaring removal.
