Just ran across this story
Just ran across this story and it gave me flashbacks of when I was stationed in Germany. Martens (like a ferret) eat EVERYTHING in or on your car and US cars seemed to be more susceptible than European cars. The speculation was that there was fish oil used in the mold-release products when making hoses and trim that European car makers stopped using many years earlier.
I remember turning down my street one night and seeing a marten standing on it's hind legs against a car side door and ripping the insulation off around the top of the window. Not long after I had chunks taken out around my Corvette windows. I also ended up with a ton of dog food and Milk Bones on the top of my engine, so it must have been a great place to relax.
