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

Hi Randy,
I have used repeated applications of motor oil on my Collins bakelite knobs.

Hi Randy,
I have used Amorall successfully to bring back the luster on both
knobs and black wrinkle finishes. KF6KXG Mike
