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. ?? <L> Lou Judson Intuitive Audio 415-883-2689 On Mar 1, 2015, at 6:46 AM, Tom Fine wrote: > I am right now working with tapes from 1959 and 1961, 3-track 1/2" tapes, with splices "replaced" in 1971 (according to documentation on the boxes) and, in the case of 4 reels, splices cleaned and/or replaced in the early 1990s.

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. > > Bottom line is that there seems to be no "permanent" splicing tape, it all seems to ooze and/or dry out over time.
