I never really understood using the film. I know what it's for, but most times, it ends up like the OP's. Tiffin used 3m for a while, then the Diamond Shield. Though the DS was better, I've still seen the mildew behind it in time. I think if I were to purchase another MH, I'd request leaving the film off. We drive our regular vehicles around for years without the stuff, and sure we get a few chips here and there. But, what looks worse, a few rock chips, or that film in the OP's pictures?

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
