Tiny, I would seal it, but I still need to get the rust out, and as for it being expensive, it isn't any more than a new tank. Anyone know how much the sealers cost right now? I've seen from $60 to $160 so I don't know, but I did do a search and didn't really find anything to tell me. If it's $160 I don't know if it would even be worth saving the tank, even if it is in good condition. I'll try to see about getting the water hose fixed(the pipe broke off that the hose attaches to) and then I'll try to get it all out, and then the sealing, if it is worth it not to buy a new tank.
