Separating Panel?

[Cameron Smolinske]

Noticed these marks (circled in red) and curious if anyone believes this to be the start of the panel separating? There isn’t any water leaks or anything of the kind but more concerned of failure long term. Tank is a 2016 SCA. TIA!

Do you have any older pictures of the tank? Were those marks there before? Have they gotten bigger? I’d measure them now to track if it’s spreading

Seems to be something that’s been there and I just didn’t notice - photo from 2023.
