Member GMCJOE did an excellent post on this topic a while back;
I just looked on the Krylon site to see if their "Jade Satin" was still available and sadly no dice.
But his post was very helpful and I think there must be a close enough match still on the Krylon site but maybe just under a different color name?

Glad I saw your post though; I was just about to go about replacing my Temp Gauge and I woulda sprayed the whole glass with foam glass cleaner for sure if I hadn't seen this post.
