harold1946 - Thanks for the referral, (Plexi film) I had never heard of this, will check this option out!
3M makes films for plastic (say, taillight covers) - but none of them that I've seen are "clear" and will badly distort the view.
D3500ram - interesting comment and yes, I would be willing to apply a "sacrificial" film over the outside of my windows knowing full well I would have to replace it when it become too scratched up - as long as I could safely remove it without using a razor blade and scratching the underlying plastic.
More to come, thank you!
