Haven't had much luck with stopping the fogging inside the GoPro camera case. I have an HD Hero2 and use Rain-X Anti-Fog, but it doesn't really work too well. Anyone found something that works?
Be prepared for a flood of "I do this and it works" posts
Here's what I did to stop my GoPro fogging... bought a Contour Roam 2.
With my GoPro HD1, some methods work sometimes but nothing works all the time. It's bloody annoying.
