Again most definitely not.
A polish that is good on stainless steel or chromium should be kept away from most soft metals especially gold, silver, platinum, pewter, copper and precious pieces.
If it is hard enough to cut stainless it will gouge soft metals easily and remove unnecessary material. If it is good for finishing aluminum it probably won't touch chromium, bronze or stainless steel.
That is not to say that a polish for fine or precious metals won't work on harder metals. It will cut slower. But a polish suitable for cutting hard metals from rough finishes will tear gold and silver apart.
