[Aus78Formula]

Silver is one of those colours that suits some shapes and not others, and the paint has to be mint and super glossy, in order to look only good and somewhat shiny! Naturally, it can be hard to get every panel to match, being metallic, call that original since they were painted largely in pieces.

As for polishing an aluminium dash, you can clean it slightly if tarnished but anything more it will only start to buff the machined swirls off. The aluminium may have oxidised below the clear coat. You can strip the clear and recoat, lightly clean and buff the bare aluminium with cotton wadding, followed by wax remover, but that's about as good as it will get. Don't get an ok dash remachined, it's still worth something to someone, but a badly faded dash will remachine just the same.
