best glue for the job?

[Ham Sulu]

I have to glue some composite quarter round molding to the base of a shower stall where it meets the laminate flooring. What's the best glue for job? Any waterproof glue? Gorilla Glue which is waterproof?

My plan is to nail it down first to hold it while the glue works as that's what I've been told is the way to make a tight seal.

Thanks!

Silicon sealer. I just removed a shower stall sliding glass door in a fiberglass stall, that was glued with silicon, and destroyed the aluminum track prying it off.

I put mine down with a good gob of clear silicone caulk behind it.
