What kind of BB was in it, anyway? It sounds like it was an unlubricated steel cup, someone mucked it up during the original installation, or it was Locktited into place.
In any case, clean and chase the threads really well and use anti-seize!
It was bright red goop... was a shimano cartridge BB. I don't think that locktite was used, just no anti seize.
There is still a fair bit of corrosion in the BB shell and the threads... what is the best way to remove this? I have tried with a steel brush but it isn't cleaning it off.
