Hello all- We have a 2010 Starcraft and after perusing the roof a few days ago all the caulking looks good except for the area around the crank-up TV antenna so sealing is in order. Before I attempt...
If you are going to use Eternabond tape, I would suggest to make the surface as level as possible. That may mean the removal of some caulk. Also, the tape works best when the surface is beyond just a simple cleaning. Eternabond recommends using their cleaner but I would believe alcohol or acetone would work as well.
