I wondered about that, I will give it a shot and I guess if all fails new tanks are about 140 bucks or so. Its possible it could fail a pressure test but its pretty solid, or it seems to be but there sure was lots of crap in it. Also its important to note that this has been done once already but dear ole dad never recoated the inside, so its on its second go round of cleaning. It may be a little thin in some areas.
