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

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

I'm currently using McGuire's Mirror Glaze 9, "professional swirl
remover 2.0". *It does the job and provides a permanent finish and is
easy to find.

I use a buffing wheel, but run it with a variac at lower RPM's so as
not to burn the knobs/plastics, etc. I just use the white buffing
stick for rouge and it really brings stuff upto a really nice shine.
Of course I have two buffing wheels, one for plastics and the other
for metals, never use the metal one on plastics!

Thanks for all the great ideas. I am going to order the Novus Plastic
Polish #2 from Antique Electronic Supply. That seems to do a great job
for a lot of different plastic items. I will give that a try on the
bakelite knobs.
