Just to name a few...
- Dry glove o-ring lubrication is critical to a good seal
- Computer battery port covers
- Camera housings
- Rebreather fittings
- Dive Light battery compartment o-rings
Thanks for the reply. Well I don't dive dry neither rebreathers so I can't comment on those but for the rest is grease really required?? Actually I avoid using it on things like my camera and torch (unless I am somewhere clear eg at home) because greased o-rings become a magnet to all sort of dirt. Anyway I think I got the point.
