Over time Nevr-Dull will abrade away a soft metal such as silver, for a silver plated contact I would keep Nevr-Dull away from it as it is a very very abrasive cleaner. It will remove hardened cured epoxy from chrome, so that should give you an idea of how aggressive it is.most use nevr dull on their contacts
Yes, but it is not necessary, in my opinion. For threads I use Noalox and after a while I will clean off the thread with alcohol on use an ultrasonic cleaner and then reapply Noalox.can you use the cape cod polish on the threads as well?
It dries out over time. I prefer No-ox-id for threads.i heard noalox builds up over time on threads, not sure if there's any merit to this statement but if true it would stand to reason that it would be even more pronounced on a copper mod. just food for thought...
