It looks a whole lot better now, good job on getting things well underway. If the PO's painted initials and the "Custom" label, aren't under a clear coat, and are just applied to the finish coating, it might come off with a light rubbing of a clean cloth and a little Goof-off. I had good luck using it previously, I took it easy with the rubbing on the painted lines I wanted to eliminate, and kept the Goof-off to a minimum. Others here are more knowledgeable about this, someone will be along to recommend something shortly.
