Discoloration under clear bra

Ours is a mess, it's a well known problem, don't know why they keep pushing them. Next coach we get, will not have anythibg on..

I would suggest you remove it asap. We waited too long and it's now a terrible process to remove it. It took us 2 days and 2 people to remove ours. Use a heat gun (not too hot and not too close) to soften the plastic, then use a plastic scraper to slowly and carefully remove it. Once you get the plastic off, use Goo Gone cleaner to remove the adhesive. Put the Goo Gone on a rag, apply, wait a couple of minutes, then wipe with a clean cloth. (wipe hard). Most body and paint shops that specialize in RV's can remove it but they wouldn't guarantee that the front of the RV wouldn't have to be repainted.

If it is black, then you probably have mold growing under it. Only to fix is to remove the bra.
