I recently bought a single din storage tray, that fits below my headunit. It has a silver door, and my initial thought was to spray it black once I had done a trial fit to make sure it did the job ok. However after fitting it I thought the silver didn't look too bad as it fitted in with the silver trim on my HU.
I have now had a rush of blood and removed and painted the walnut items mentioned above, along with a spare set of door switch trims.

Really not sure what I will think of it, but to keep my options open think it would be a good idea to have a spare set ready to go back in.
I'll post pics next weekend when I get the silver items fitted.
