Paint color match for old (or new) LEGO grays?

[BraselC5048]

I'm wondering if anybody knows of a reasonably close paint color match for preferably either old light gray or old dark gray, although if not, either of the new grays would work too. Hopefully something that also comes in a spray can, since I can't brush paint with most paint brands (or really anything that comes in a glass bottle). I'm intending to paint some old parts that only come in clear colors into gray.
