I am glad that you found a tank, it'll look way better than bright red fire extinguishers, gotta tell ya, I 'm not a fan of the brass and copper ones either.
Looks like your off to a good start now, there are few things as treatable as UTS (ugly tank syndrome), some of us get it and don't even realize we have it. Did a friend tell you or were you able to diagnose this on your own? Doesn't matter, you're cured!
