I've never removed it, but others have around here while installing their gauge overlays (see other forums).

The reflection is not that bad... I don't use dash protectant either so mine is not overly shiny either... it's just something that I notice often while I drive. It does not really interfere with anything but I prefer as clean a windshield as possible.. and no reflections if possible.

I sit pretty high in the truck too.. this may not be a problem for shorter folks (below 6'3")..
