What does the rest of the hammer assembly look like ? Knuckles ? Hammers worn
down as well ? Maybe time for something a bit more extensive ?

I personally like to repin if everything else in in good enough shape.  I have
little faith in chemicals, after time and time again experiencing their on and
off again functionality. Never met a liquid lubricant yet that worked much more
then half the time.... and going the other way around ???  hmmmm.. I dont know
if I would even try.

Repinning is a nice skill to get down. You can often do a really bang up job of
it, better then factory work, and you can use the opportunity to even out other
friction issues as well. A great excuse to do the 60,000 mile full service
routine :)
