As folks have said: use 3M 5200 if you plan on never removing the screws or the mounting brackets. The mechanics at the marina told me to use 3M 4200 on removable mounts and to seal mounting screws. Check out the 3M web page and check out the applications, You will see the 5200 is for a permanent application and the 4200 is for removable application.
