So my computer area is under these shelves where I have all my tools and components for electronics and soldering. Well I have to big orange handled ratcheting screwdriver, and it had a really fine flathead tip in it. And it fell on my Macbook and put a nice little gash in my shiny smooth lcd. It's about an inch long and at that angle where it magnifies the pixels it's over. What can I use to buff it out or fill it?
