You don't need science to tell you the material composition of some crap tank sealer that's broken loose and floating around in your tank clogging up your filter.
You could just read the ingredients while you're sitting in your garage pissed off because you not only wasted money and time, but now you have to do it all over again, only this time it's harder and takes longer, because it's not rust or pinholes, it's some Elmer's glue crap that only comes off when you don't want it to.
