I've recently completed a 1/48 scale Lunar Module (the Monogram model reissued by Stevens a few years ago) and am looking to produce a more realistic moon surface for it than the plastic one provided in the kit.
Basically, my plan is to convert a small unusued fish tank into a display / diorama. I've put black film against the rear glass of the tank to simulate the sky, and now I'm just looking for a good source of fine gray powder to use for the surface.
Can anyone recommend a good (and preferably inexpensive) material to use for this? I might also add a few simulated moon rocks in to the mix, but primarily I'm interested in just the surface dust / powder at this point. It doesn't have to be perfectly realistic, just something fairly representative of the proper color and texture.
Thanks in advance for any advice you can give!
