Tuono, given what i've seen done at my local auto/motorcycle film protection store, most anything can be wrapped. Whether or not it looks good on a windscreen is another story. I'm speaking specifically of 3M type film and not generic "window tint" film. I'm not sure if the typical window tint film can be applied or not with success due to the materials involved. Ask your local installer, he/she should most definitely know.
