Hi All — I'm off to shoot a short film in Togo in a couple of months with my GH1, and am concerned about protecting the camera and lenses from dust and humidity. So far I'm planning on storing all of my sensitive gear in waterproof bags with fistfulls of silica gel packets for the humidity, but from what I've heard the conditions are generally very dusty, which can take a serious toll. While out shooting, some people have suggested covering the camera in plastic wrap, and I was thinking about slicing up clear plastic bags to make a hood that would leave better access, but I'm concerned that either method might cause the camera to overheat (looking at ~30°C daytime temps).

Any techniques that have worked for you in the past? General tips?

Many thanks!
