The letters are almost gone on both cups. I dont know how they were made but it looks like a bad pressing. The left cup has a ruff feeling to it like it wasnt sanded before the pressing. Its hard to explain and hard to get a good image of the issue.
I think what I might need to do is strip the anodized layer off, buff the cups, paint and get some sort scratch on lettering. Then a clear coat finish to finish it off.
