? for Paint experts...

Well, I just called the place that painted it - surprisingly, it's still there, and the same guy owns it. He wasn't there, but hopefully he'll call me back and be able to remember what type of paint he used.

If that doesn;t work, I'll try a small patch in the engine compartment under the battery tray. the vaccuum canister mounts there too, so you'll never be able to tell if it gets messed up.
