Hey F5 I cut my chrome windshield and the chrome didn't flake off, but you have to becarefull you don't rub your shears on the back side of the windshield. That will take the finish off, I have a few small places where I nicked the inside with the tip of the shears when cutting it, but I was lucky that the windshield piping covers them.
I will try and get a few pictures of it, but it might not be till after xmas
