Loctite will work on the bolt, if not stripped or nut not lost. Spray foam in trunk lid and dampening over it will help, other areas around the trunk may need work after. Peal and seal is decent stuff, had it in one of my cars an never came loose for the yr I had it. They currently make a different product with a buytl base thats a few bucks more then peal and seal as well.
