Bear Damage! - Alternative Siding Ideas?

[azapplewhite]

Have had a 30' Diameter Pacific Yurt as a weekend "off-grid cabin" in the Sierra Nevada mountains for 15 years and it has been fantastic. I NEVER store food in the yurt and never have any trash or garbage around. I also always leave a few open bottles of Pin-Sol whenever I leave because allegedly bears hate the smell but this may be urban legend! This worked great for 15 years but I think climate change is putting more stress on the bears.

A bear broke through the french doors 3 weeks ago so I welded up some channels to protect the door with 3/4" plywood but last night, the bear pulled the siding down but thankfully stopped at the "trellis" siding.

I'm thinking about replacing the canvas siding with metal siding like Galvalume corrugated metal or something similar? Anyone out there have any experience with this or have alternative suggestions?
