TriFlow does leave a dry film on the surface, and as you say it persists
for a long time. I think it's good for sliding surfaces that are under
moderate to heavy load, and do not require absolute minimum friction.
GLY2100 is great if you've got it, but it can be hard to get, and the
only people who need it are owners of late model Studer machines, or
someone who maintains them. Here, for those who don't already have it,
is the official Studer document on capstan motor lubrication:

They do stress that only the original lubricant should be used, either
PDP-65 or GLY2100.
