You could try a product found at Best Buy stores for repairing scratched CD's/DVD's. I believe it's a cream or lotion that fills scratches in. It should be tested on something similar to your screen (plexiglass scrap?) so you don't cause further damage or blur the screen material. Hope you have luck with this project. You might just try to return it to manufacture and upon the next install cover the screen with cardboard and some vinyl tape. Good luck either way!
