Painted Gas Cap

So I am needing to replace the gas cap on my Volare Kit Car and wondering what is out there as I will need to paint it, most available are chrome caps but that is not what is supposed to be on there and I am coming up empty on ebay for paintable caps, any ideas?

Cover the back side of the cap and bead or sandblast it. EOP

Well, the chrome replacement caps have a plastic handle on them, and the original one that I lost had a metal handle on it that is where I am having the trouble finding a metal gas cap with metal handle that attaches to it instead of a plastic one

Got it all figured out now, thanks
