Default Re: Translucent Tuning Dial 'knobs' - re-manufacture?

If you look on post #3, you will see the cone shaped central nut looks perfect. It didn't look like this when I started.

I hold these in a lathe's chuck and polish them while they rotate, then de-grease them with contact cleaner , leave for 24-48 hrs to acquire a golden look then spray with Holts duplicolour automotive clear. The Holts sprays are a very fine droplet lacquer with a quick drying solvent.

There is also a metallic gold Holts that can be used to restore previously gold painted surfaces. You certainly don't want to use any old paint for this task, it must be one like the Holts that can be applied progressively in very fine layers until it is just enough. Enamel spray is totally unsuitable.
