Cement Coping: 2 x 4 Marks in the dried coping: how to remove them?

[Curlenjik]

I sent you a reply from my e-mail,. And I also sent the pictures of the coping. These are new coping pieces and were installed as you can see when there was NO water in the pool. The pool plaster itself has been demolished. I cannot go further and replaster the pool until I resolve the coping question.
