I was PMed and asked what some of the previously shown paints were so:

On the control arms I used Krylons 1307 battery protector spray it dries like a paint. It's not the tacky coating some of us used to know. With just a practice run on a similar metal and you'll know how to achieve the effect you want. The other paints were what I experimented with at first.

Krylon stained glass (9035 Canary yellow) for the yellow, which I found at Hobby Lobby.

The Copper color is Dupli-Colors (MC205 ORANGE ANODIZED) METALCAST anodized surface color system (just a paint) and I bought it at a Napa paint store.
