I wonder if anyone has experienced this problem. I have a 5D mk III and it's about 2 years old. recently I was in holiday in Vancouver and the weather was warm but not too hot; however the white paint on the Canon logo at the front of the camera has started to run and smudge over the front of the camera. It doesn't affect the camera operation but it looks cheap and nasty.
The camera is going back to Canon next week, however i am curious if anyone else has had this problem.
I have two 5DIII's and a single 5DII, all bought a year apart. I've used them quite heavily in a professional capacity, shooting a lot of weddings and I've not had this issue. But it wouldn't surprise me if Canon had a rogue batch. Stuff on the production line some times goes out of spec due to suppliers supplying out of spec paint.
