NCarv, not sure but it seems to me that Stabilant might be related more to Tweak. If I remember correctly Tweak was polyoxyethylene and polyoxypropylene. The problem with Tweak was after a couple of month, the contact fluid had turned into an oily mess and one needed to clean the connection since the sound was degrading.
OTOH, have used Kontak for ages with no apparent degradation of the sound over time. (that is other than needing normal cleaning.)
