Hey there. I bought a 525xl and it had a scratch on the inside glass. Someone else on this forum posted a thread about removing a scratch with diamond paste, and it seemed convincing. I used the paste to take the edge down and when I filled it with water the scratch is 99% invisible. I couldn't even believe it. Not even kidding. I took pictures of the scratch before, and it was 2 inches long and deep enough I could catch my fingernail on it. When I look at the tank now, I can barely find the scratch even though I know where it is.
The water is definitely helping though, because the scratch was more visible when the tank was empty. Not sure if that process interests you but it could help take the visibility of that scratch out. Have to be super, super, SUPER DUPER careful working with that paste though.
