I had GH2 fell into the fountain, dried it up, still working after 3 years, hope yours will work, best thing is to dissasemble cover parts, so you can dry it asap.. Good luck!
My GH2 fell into the sea with RC helicopter. Is there a chance to save my last video file?

open it up and seperate out as many of the components as possible. The salt will corrode things very quickly if not cleaned off with a soft toothbrush and some component cleaning solution. The battery will be gone but that is an easy fix.
The quicker this is done the more chance you will have of survival.
