What grit sandpaper did you use?? To fix it you have to move up in progressive grits until it becomes clear again. I have a Micro Mark finishing kit that I bought for model cars and guitars that works well for clear plastic. The kit ranges from 2000 grit to 12000 grit and is followed by fine polishing compounds.
