Wow, that is a dramatic difference! EVERY radio I have that I bought from Japan has this issue.
Time for some serious polishing action!

Never Dull Wadded Compound. What is it? What can it do for you?

You wouldn't see scratches because the black deposit that comes off on the cloth when you polish is - in the case of vac plated plastics - part of the silver nitrate-based compound that forms the bright finish on the plastic. It's not as tough as chromium plate which, along with the mention earlier in this thread of the cloth bringing off with it a black deposit, leads me to believe that you wouldn't be able to make a weekly or even an annual job out of this because the typical thickness of the layer of silver nitrate used on plastics for this purpose is many times thinner than a human hair, a thin one from a blond head mind, not a thick one from a ginger pud.blu_fuz said:
It might be worth experimenting with polishing the piece once only, then using a tack cloth on it and spraying it with clear coat to maintain the shine. That should last better.

But that's a different piece, now do the first one again and see how much silver nitrate remains afterwards..
Even Solvol Autosol, as Rick mentioned, will eventually lift the shiny stuff off completely. It, and Silvo which is another product that has exactly the same materials code as the Wadding in the title of this thread, so is the same thing, will remove even harder chromium plate from copper backing as used in car trim parts eventually.

Sometimes the chrome trim on C-100s is already pitted down to the copper coat, usually green spotted before polishing..
My Korean Conion is like this, my Japan C-100s were nicer condition chrome..

Yes, but maybe with a few good smooth coats of clear lacquer, the shine could be preserved forever and not be in any further danger of going dull or breaking down if it needed to be cleaned. My JVC PC-11 had some pitted areas of plating when I got that a few years ago and I used Silvo on it to great effect, but then it started to go dull again and fortunately, I only tried a very tiny area that time before realising that the silver compound was coming off in greater quantity than it had that first time.blu_fuz said:
It's like using polish on a car; every time you use it some paint comes off but automotive paints are very thick by comparison with flash plating.
On the other hand, when the original surface does start to come off to a noticeable extent, you could try some of the new types of surface coating which apply silver nitrate to the surface by spraying, no chemical baths required. Usual safety precautions apply; gloves, mask, goggles, etc:

I haven't tried that one but I fancy giving it a go, some cheaper types are available in the UK which do the same thing.

Im such a big fan of chrome on boomboxes. The more flash and bling, the better. For me anyways. I find myself buying most, but not all of my boomboxes mostly based on appearance. Great sound is just a bonus 
I love a good feast for the eyes while playing my music. Great job Vintage Man!

So there ya have it brothers. I must say I only use this on parts removed. I would not try rubbing this around painted surfaces.......

I have been using this product forever...BUT you have to be careful with it. Like Vintage Man said be careful around painted surfaces...and be careful if you are doing chrome trims while they are still on the box...this stuff leaves a "whitish" film when left on to dry, but if you are careful it is a pretty good productVintage Man said:
