Cloud Dancer I was afraid to remove that strip also so I only peeled it back several feet. It was wet and moldy inside. I decided to seal the upper and lower portion of the vinyl trim rather than remove 30 ft of it and that worked. The 5200 should work a lot better than caulk because it is an adhesive. Before I found this leak 30 ft away I was convinced that my AC gasket was leaking water was running under the rubber roof to the rail, that was not the case but I tightened the AC gasket anyways. Just a few turns with a small torque wrench for an even torque down. Good Luck to you.
