Hi Doug,
Forewarned by your Tip #1, I was very careful never to raise the arm when it was locked down. What I did do, however, was to leave the arm resting on the cueing bar, lever raised, rather than on the arm rest, lever down. Over time, the weight of the arm itself apparently was too much for the seal. Black goo oozed. Ugh.
So, maybe this should be Tip #1a: Always return the arm to its rest and lower the cueing lever to prevent the oozing of black goo.
