We had a similar problem with the decorative stripe on our 86 excella. While powerwashing, I noticed pieces of it flecking off. Seventeen years of u.v. fade had also reduced the original royal blue to, you understand, a charming and revered color. Carolina blue.
We had the tape replaced by Steve Ruth, at P & S Trailers in Ohio, an A/S advertiser. < www.pandstrailerservice.com
They stock large rolls of the tape and perhaps they have the "limited" tape too. The charges were reasonable and when finished it made the unit look like brand new. Although it's only a cosmetic item, you are still not putting lipstick on a frog. Style.
