Restoring RH handlebar control knob

[markb]

Anyone have a good method for restoring the color to the RH control knob.  I need to save this rare pointerless knob.  It seems like there should be some kind of polish.  I was even thinking of using a semi-gloss black paint.

These are UV that are responsible for its state whitish... You can bring back it to its original appearance with polish for painting car and a soft tooth brush.. It is completely recoverable because mine was worse... (state same as that of the photo)... Here it is now on the second picture and it is not yet finished.
The polish is going to regenerate the surface by removing this fine whitish layer...

Your results look great!  I tried googling "Johnson Polish Renovator Special" with no luck.  Where can I find it?

Mark,
Sincerely, I do not know because this product was purchased about 1985, at the time most of the paintings did not varnish and they are oxidized and tarnished by the sun.
Today this product has become completely obsolete because all cars paintings are varnished.
The brand Johnson is U.S... Why not try to contact them?

These are the Ebay item numbers but in the UK, I would have thought they do something similar over in the U.S.
Thanks Garry

Thanks for all your help guys!

[4pots1969]

The thanks is too much... A good restaurant will suffice!!

I'm guessing it would have to be Japanese. 

[4pots1969]

Not necessarily...  I leave you the choice...

Here’s a product I found that is supposed to remove oxidation.


I made amazing progress in the first 5 minutes using a toothbrush.  But ½ hour later it didn’t got any better.  I think it’s still too grey.  Would some plastic polish help?

Anyone ever try black shoe polish?
