That can be fixed. you just need to sand it flat and shoot it again. Use a random orbital and start with 100 grit and go through the range up to around 320 to 400. Even if there are still tiny dents, if they have some of the new clear in them, it will stick and they will fill.

When you start sanding it will freak you out because it will turn white and look like it is ruined. Take your time with the 100 and do not go to the artwork. After the 100 the paper will not sand as fast and you shouldn't be able to get to the art if you keep it totally flat. Wipe it with Naptha once in a while if you want to see the white go away and make sure your artwork is still ok.
