I'm getting a little tired of replacing old dried-out foam blocks to
hold down the ends of 1/2" tapes. Worse, some of the ones I've fished
out have utterly crumbled over the years, leaving bits of themselves
inside the reel.
One thing that I recall is that many tape manufacturers used a blue,
sort of "sticky silicon" tape to hold ends in place. This stuff never
seems to degrade.
Does anyone know what the stuff is and where one might get a roll of it?
