I remember Julian Dyer saying that repairs he made with Scotch
Magic Tape are no good over longer time.  I repaired my first rolls
with the Magic Tape 18 years ago, and it is still absolutely fine.

After Julian's comment I switched to Neschen Filmoplast P, which
is a paper tape that does not shrink and has an acid-free adhesive.
(Filmoplast P is transparent, P90 is white; both are fine but the
transparent P looks nicer, of course.)
