Wet Cement

Here's a plain gray creme, Xtreme Wear Wet Cement:

I keep buying grays but really I don't wear them much, when it comes right down to it. I do like this one a lot, though. It's a fairly cool medium-gray and it really is pretty close to the color of wet cement. I don't think this polish is current but it was around for a long time so it might be findable on Amazon or eBay. Even if it's not, though, this isn't really a unique color and I'm sure there's something similar around.
