And following up, there is generic blue and then there is Scotch #67, which is all I have ever used since high school in the 60s… :-)

> Tom, is there any way to tell which splicing tape it is, the pale blue or the white? I'd be sad if the 3M blue tape is doing that - my tapes form the 70s and 80s have Sticky Shed, but the blue splicing tape is perfect, peelable and replaceable... not oozing.

Alas, every splice so far has needed new cleaning with Naptha and many of them -- even those cleaned and successfully played in the 1990s -- have required full replacement.
>> The replacement splicing tape put on in the 1990s has proven mostly stable but there has been some ooze and stiction around some splices. I tend to believe that is leftover ooze from non-complete cleaning of the original splices before replacement, but it could be new ooze over the past 20 years.
