Well, this isn't like the hull type gelcoat. Just a bulkhead. In the first two or three months of boating, the factory screwed in fiberglass cover came loose from the vibration. After I did the track screwed in cover it never came loose again. Glue is good too. Not sure how you would get the two tracks to stay where you want them while the glue is drying. Maybe two screws on each to keep them in the right placement while the glue dries.
