So the color is great but if you run your finger across it a white scuff appears. Washing removes the scuff but this really shows the lint.
It looks best when wet as a flat deep brown.
Is there something I can rub on the parts to get this wet look?

2 options.

Hard anodising is durable, most auto parts use it.
You will need to outsource this.

Clear-cote aka lacquer, may work depending on use.
