I've used polishes like this before

Autosol Anodized Aluminum Polish 75ml Tube

They do quite well on the metal but tend to make the plastic look not so great which is a problem for W123/6 trim as it is often inbedded in the stuff - so you kind of go round and round with aerospace303 and then the metal polish...
