planet bike fenders

To anyone who knows about bike fenders and/or bike maintenance, can you please help me?
I have apparently scratched my bike fenders and I need some suggestions as to how to remove the scratches from my rear fender. Any ideas?
Note: The fenders are polycarbonate plastic and also could I fill in the abrasions on the “Planet Bike” font script back to good condition?

Plastic mudguards scratch easily, if you plan on trying to fix every scratch that will happen, you won’t have much time to ride your bike.
