Restoring RH handlebar control knob

[markb]

I do have a couple and I thought of that too.  I'm not sure I have the skills for that.  I had enough trouble with the sandpaper.  But I think I could find a die maker that could make quick work of it.

I do not think that the painting is the solution to the problem because the knob is submitted a manipulation and early where later it will take to undo to remake a new painting.. Not good...

I agree with Gerard.  

Is the surface smooth ?  If so, have you tried actual aluminum polish to bring out more of a shine?   Simichrome is, imho, the best.

I would have no hesitation modifying a pointer knob.  Do you have a spare ?

I sent you an email.

Mark, I'm sure you can save this knob... Because the original knob will be better than a fake, and you will feel better to know that it is true...
We must think to find the correct method, even if it means leaving it aside a few days after returning with a real solution...

I haven't tried this with a black kill switch knob but maybe worth a try. If you have a redundant knob then give it a go.
