I've found Eastwood's paint to be high quality. The other spray bomb manufacturer with excellent paint is SEM. It used to be available only through automotive paint suppliers but now it's available on Amazon.
In an earlier posting I mentioned Cerakote. Other than it being available in hundreds of colors, one of the nicest things about it is, it's a very thin coating, so it doesn't hide fine details or textures the way powder coating does. It would be the perfect finish for restoring Campagnolo wheels. Because it's an air-dry coating, as opposed to a baked coating, you shouldn't have the out-gassing problems that you do with powder coating. I've even had my throttle bodies and linkage Cerakoted. Try that with powder coat!
