Looking at my options for fixing some surface rust on the inside of my tank. I like the POR-15 kit that has a sealer in it, but I'm not sure how well it would work in a 60 tank. My main concern is the "box" that the fuel pickup sets in, and whether the sealer would end up clogging that little piece of hard line. If any of you have tried the POR-15 sealer in your tank and can report the results I would appreciate it.
