I know I should have searched it on here before buying my first card scrapers, but it is something I should have done years ago. I won't say I'm a expert at using them yet but the stuff I can make disappear is amazing! I can't wait until I get them all figured out. Now the problem! I don't someone with OCD should be using them, I fixing scratches & tear out in place that will never be seen, just because I can!
