On the 3 tanks I had experience of it would be very difficult to clean them to the sort of standard where I would feel comfortable using sealant . I bought some POR 15 after some research and also cleaned my tank using proprietary acid and cleaner but I checked the internals using an endoscope and wasn’t happy that the sealant would be a permanent fix
I’m sure others have had success with sealant
