I think it may be safer to wet the tape (assuming that works) without straightening it first. It seems to me that straightening it could apply enough force along the tape axis to pull off the oxide.

When I get a chance, I'll look through my smallish pile of TU58 tapes to see if I have any other not-so-precious ones with stuck bands to try.

Unfortunately, I made the mistake of trying to boot my VAX from the most precious tapes without any special preparation, so if any of those had stuck but not broken bands, then those tapes have already shed oxide. Hopefully in a non-critical area of the tapes, but Murphy suggests otherwise.
