Weathertech apparently makes headlight protection clear film. They don't make it for the Z yet but I did submit a request to see if they would make one. How many of you all would buy this if it were available? I checked on some other cars and it's ~$50.

edit: after getting some good advice and researching a bit more, it sounds like this may be a BAD idea.
