Anyone have some ideas on restoring some old black knobs to the
original glossy finish? These are the black knobs possibly made from
bakelite? used on the HQ-170 receiver and many other old boatanchor
type equipment. I have a couple of the knobs on my old AT-1 that have
gone dull and I would like to return them to the nice glossy finish?
Thought about cleaning them real well and then spraying them with some
type of clear glossy finish? Possibly there is a better idea out
there. Thanks & 73, Randy, w5kcm

The problem is that the surface gets etched, and you need the surface to
be smoothed out. Green jeweler's rouge on a rag and a little elbow grease
will do wonders.

I tried toothpaste... it is too fine. Just takes forever. Might be okay
to use toothpaste with a buffing wheel but definitely not by hand.
