This has become interesting...a few weeks ago, on my trip down to San Felipe, a large pigeon sized bird made a mistake and bashed right into the middle of my passenger side windshield. While I was traveling at 55 MPH.
It left a mark, but not in my line of sight so I didn't worry about it then. Plus it's not all that obvious, sort of a baseball sized ghostly mark. A few days later, tried washing it with soapy water. The mark wasn't impressed and stayed put. It's kind of sticky. Hmmm. Next I tried Awesome. Nothing. Still the same mark.
OK, brought out the big guns; WD40, Goo Be Gone, Carb cleaner Spray, no change. What is this bird made of??
Anyone have any idea what kind of bird leaves a sticky mark when it flies into your windshield?
At this point, not even sure I want to clean it off. Makes a conversation starter. I'm not even all that disappointed in those cleaning products, I'm impressed by the birds physiology.
