    If I want to model rock faces with spackling, would aluminum foil wrinkled up work? or whats my best option?

    Mike,
    I've used spackling to represent paved roads, & to fill gaps, & such, but I'm not sure that it would be a good material for representing a rock.
    My favorite material for making rock faces is hydrocal plaster, or plaster of paris.
    Lately what I've done is wait until the plaster thickens up a little, & just glob it on to the spot where I want the outcropping. When that has set up, I take a skrew driver, & drag it across the plaster, cutting striations, & broken places in the rock.
    To paint the rock, I always start with rubbing alcohol, & India ink in a spray bottle. This makes a black wash that gets down into all the cracks & crevices. Then I color the rock further by lightly brushing on various earth-colored acrylics, ranging from dark brown, all the way up to white. Remember, a little color goes a long way.
    I have used tin foil for making rock molds, pouring the plaster into the mold, & slapping the mold down where you want it, & letting it set up before eremoving the mold. Painting is done the same way, regardless of which method you use.

    Mike,
    I just re-read my reply to you, & I wasn't real clear on that black wash.
    If you're not familiar with India Ink, it's liquid black ink, & you can find it in office supply stores (Staples, Office Depot, etc...)
    I mix my black wash in a little 8oz. spray bottle, with about 8 or 10 drops of ink to 8oz. rubbing alcohol.

    Thanks Charlie, That probably would have been another question a little bit later on. I appreciate it.

    Hi Mike,
    All those ideas are great. i found a spray paint that looks like real rock when painted on the surface. Its called Speckle Stone, by Crown. U should be able to get it in hardware store. i can get mine at Revy and Home Depot. Its main use is for fire places. Still u should use india ink or paint to prime your surface before puting on.
    Greg.

    Thanks Greg,for the information. I bought one rock mold the other day, works real well, as long as I can be patient. Tommorrow night I'm gonna try a cast in aluminum foil to vary my rocks. I appreciate all the great information guys. THANKS
