I am really happy with the response I have recieved on this. A couple of people have requested painting instructions so here it is... Sorry this may not be posted in the correct area.
Base coat with black acrylic craft paint. Let dry. Sponge on light gray (leave some black showing through in some areas) then when still wet, brush over it lightly to soften. Let dry. Add a little white by pouncing it on with the end of the paint brush.
Now, if it still doesn't look quite right (after it dries) just keep fiddling around.
(my favorite part)
I thought mine was still a little dark so I lightened the gray and did a bit more.
(just use black and white and mix your own gray to the color you like)
Actually after all the goofing around I probably ended up with a couple different shades of gray in there.
That's it!!
