Adhesive to re-glue the rubber gaskets under the floor

[Twinbrook]

As I pull up the floor to go down to the bilge area the rubber gaskets are just pealing away. They are in excellent condition and a little goo-gone takes the now slime adhesive right off. What can I use to re-glue them back on and not fall off because of the heat. This is rubber to fiberglass.

Check out 3M weatherstrip adhesive. It works well for applications such as this.
