What paint does ge use for their fixtures, or what is a close spray paint match?

Krylon makes a close match...found some on Amazon.
Krylon 5531 gloss pewter gray.

what about Rustoleum granite gray?

Never used it...I found Krylon a better match many years ago, and continue to use it.

Might look into the Krylon 5531 paint if I ever decide to repaint my GE Crimefighter. I got it silver painted so I repainted it silver when I restored it but I suppose grey would be more authentic GE.
