Is this pitting?

[sensibull]

OK, so last night I acquired a keg that someone had already (but none to skillfully) cut a mouth hole into, but allegedly never brewed in. I thought this would save me the trouble, but it didn't occur to me until after I bought it that this meant the inside had been exposed to the elements in whatever garage or alley it had lived in, for however long.

Anyway, besides a raggedy cut, a small section of the inside has these strange raised, rough areas that I can't quite figure out. My understanding of pitting is not a raised surface, but a sunken one.

Can anyone figure out what this is, and what I should use/do to smooth it out?

Thanks in advance...

If they cut the top out with a plasma torch it could have been from the slag hitting the bare metal. When mine were done we filled bottom 1/3 of the keg with water to try and prevent that but it still happened a little bit.

Anything I can do to remove or smooth it?

Maybe hit it with some fine grade sand paper or a fine grit grind wheel. Honestly, I wouldn't worry about it. I have been using my keggles for about two years and there hasn't been any adverse side effects yet. It's on the inside and only you will probably ever notice it

Just sand it off, and you should be GTG....

Adgreed, and if it doesn't come off, you should also be GTG...

Thanks for the replies, fellas. FWIW, some sanding did remove it.
