You have any pictures of the tank. That tab should have not broken off anywhere on the tank. Unless it was poorly welded on. Your pretty much gonna end up redoing the sealer inside the tank. You should pressure test the tank before any sealer was put in the tank to look for any pinhole leaks that could be welded up. Sealer does not cure pinhole problems in the long run. Just my thoughts.

I have never sealed any tanks. I don't believe in the stuff. I just keep on welding and grinding then keep pressure testing the tank till it has no leaks. Everyone has there preference. The one guy I have been painting for really likes that por15 stuff.
