On the silver the top is not paint. It is magnesium alloy. I don't know about the blue or green cases, but they look like they have paint on them. The top does scratch easily. It won't scratch if you are careful or you keep it at one place all the time. One thing to know is to never carry anything on top of it and it shouldn't scratch. This is from experience. I have one scratch on it but I can't really notice it because The texture of the top of the case blends it in.
