Good point- I have Inon strobes myself and as you I do use a little extra silicone grease on them to make sure the o-rings don't 'bind'
I guess it depends on which o-rings we are talking, I think for the main housing o-ring there will not be a risk of 'binding' since its a squeeze-fit between o-ring and a straight surface, at least on my Aquatica.

So i guess you have seen the same o-ring U shaped snag as me. :-)
