why? i dont think that makes any sense but im sure you can google it and find one. just be aware its going to really distort the picture especially from an antiglare screen. you do know the difference between the two screens right? i dont really think they make them for anti glare screens because it would look horrible. i googles a lot on this question and didnt find one thing, so good luck.
Film protectors for the MBP AG screens are pretty hard to find because they only represent a small percentage of the users. I do recall Photodon can do custom cuts with their film if you really want one.
However I suggest that don't do it, it will probably make your screen murky. Instead I suggest just being extra careful, clean it regularly and just buy a keyboard cover like a Radtech screensaverz to protect your screen from keyboard marks.
