You use this on bearing points between the front termination and the tuning pin
only then ?

I understood that it was recommended to apply protek to the front termination
points themselves as well.  Didnt seem like it mattered whether it was an
agraffe or a Capo bar. In the case of the Bohemian, there was a lot of squeaking
and hanging of the string in the agraffes themselves.  Proteck did fix this, and
rendering was improved.. but it didnt last past the one sitting. Next time
around the problem was back, and I noticed a green colour to all the agraffes.
