Hey everyone,
I found this old Antique sink with a 1cm drain which I play on plugging or maybe attaching a valve to for easy water replacement.
However, the tank has a few rusty spots on its white exterior. I've been told the lining it has on it already is ceramic but I don't want to risk it.

Does anyone have any suggestions for a clear spray-on lining, paste, or fish-safe paint that I can use?
I'm currently using a plastic bag as a liner for it but I feel like it's ruining the aesthetic so I want to replace it.

Thanks!
