Well, this is an IAP tank, oddly enough...
But the wife and I decided that we could tackle this.
We got 1500 grit and 2000 grit wet/dry sand paper, buffing compound, and new bonnets for the buffer and went to town. My wife was even working on it while I was away at work (she wants the tank in the house ASAP).
We did the first portion at night under halogen work lights and it looked pretty good. But in the light of the morning it looked awesome! We should have all of the buffing done this evening. Then it will be time to clean it out woth RO and vinager (or so I've heard).
My only regret is that I didn't take any decent before photos to post with the after photos.
Thanks for the input.
