"If" your referring to the screw heads gradually breaking through the thin cover tape (not a butyl putty tape) along the top of the slide, replace it with some Eternabond Sealer Tape.
I did it on my prior '05' Eagle, and just installed it last week over the 3-week old thin black tape Jayco used on my new 2018 Jay Flight.
Didn't take a pic of my new Jay Flight tape install yet, but here is my '05' Eagle slide Eternabond install:
The Eternabond is thicker and more robust then the OEM tape...., after applying the Eternabond sealer tape run a bead of clear silicon caulk along the edge of the Eternabond tape and the slide flange.
