I hope you get things working again... but.
The 7D was rated as weatherproof (whatever that actually means).
The 6D is not.
Maybe you shouldn't have cut corners yourself.
Not suggesting you should have had to pay an extra grand for a 5D3 with weather sealing, but $60 on a kata jacket or even $5 on a throwaway rain cover...
My over-riding feeling is empathy, sympathy even, but you can't really blame canon. You made a bad call, but the punishment seems undue.
EEEEEEEEEEEEEEK yikes. While I want to say, you take your risks with your gear when shooting in conditions like that, and when you do it you best make damn sure that the benefits outweigh the risks. But in reality, I take the other course way too often, forget the weather and go for it!!! a bunch of times so far this summer - hiing the trails at watkins glen, storm moved in, nothing we could do about it other than hike back. I will say my thinktank bag is why that ended up not going horribly south for me. 2nd one I got real lucky - shooting the tragically hip, this deep dark black cloud ominously moving in. The skies were intense and the images were great...but wow - you know how it goes - you get your 3 songs in the press area and thats that...so I do the 3 songs, talk to the other phtographers for a moment, and start waling to the car. Half way there i felt a sprinkle. And 10 steps away from my car it unloaded on us, freaking torrential downpour. If the Hip had come on 5 minutes later --- yikes. As it was, --- for the Tragically Hip, ---- ALL their gear was destroyed by the storm!!!!!
Thats the 2 most memorable. I take the weather for granted because of my mk3, but often forget that the 6d isn't quite as rugged.... I gotta watch that!!!!
On another note --- 2 years ago, event shooting in clubs --- had a full beer spilled on my 7d - on the backside. I dried it off with a rag and it was fine to shoot with for the rest of the night. I no longer own it, but, sold it to a buddy who took it to africa - it survived that and did admirably. When he got back, he had 1 month left on the B&H extended warranty (3 year plan, so that camera is doing quite awesome). He sent it in, the replaced the shutter, cleaned the sensor real good and replaced some other gaskets and stuff. That camera could last him another 3 years unless he wants to upgrade.
