    if you're looking to go cheap I heard that you could use Elmers Spray Glue... TRY THIS ON SOMETHING YOU DON'T CARE ABOUT FIRST!!!! I've never tried it before. If that's a no go... maybe the clear acrylic stuff they encase butterflies and junk in to make paperweights... but that's just a thought.
    Bummer is you have to worry about getting paint to stick to this after your done!
    Have you given any thought to maybe cutting out balsa wood peices to cover the foam and paint those?

    Gesso might work, but it may crack if something hits it hard enough.

    Me too:

    1) Talk dirty to it
    2) Rollplay
    3) Rub it really hard
    4) Take it out to a steak dinner and a long walk on the beach
    5) Get it drunk


    Sorry, I had to post this!

    You can brush on some epoxy resin, not polyester resin as that will melt the foam.

    Epoxy resin with some fiberglass mat, it's alot more work. But should give you what your looking for.

    I don't know what your end result will be but you could also try spackle. Works great on foam, and easy to sand.

    You can also try sculptorcoat
    http://www.rosebrand.com/product726/...2526%2BCoating

    I have used ureshell and sculptorcoat both


    2-Part Urethane, Hard Shell Foam Coating

    UreShell is our latest offering in fine foam coatings. UreShell is a marvelous hard-coat, 2-part, urethane-based coating. Its average 25-minute pot life allows for rolling or brushing. Applications cover both interior and exterior surfaces. It leaves a hard, glossy, smooth shell finish. It works great on props, backdrops, signs, molds, etc. One gallon covers approximately 320 sq. feet at 5 mil thickness. Dries to a tan color and can be finished-coated with most all paints and synthetic stucco.

    sculptorcoat
    A versatile, non-toxic, water-based plastic cream for tough, flexible coating, texturing and sculpting. Can be used as an adhesive, a sculpting medium, a filler or to add texture, and air drys to a clear or translucent finish (depending upon thickness of application). Useful for scenery and prop-making, tints, stains or dyes, as well as other textures (such as glitter, sand or sawdust, for example) can be added making Sculpt or Coat® an extremely adaptable artistic medium.
    one neat thing about sculpt or coat is, if you need to paint it with spray paint
    the paint will not flake off even if the part you covered with sculpt or coat
    flexes.

    I was pleased with both products.

    Yes, if you use viscous resin a lot of detail and sharpness will be lost. If you use something thinner, then less so.

    Does the soft foam have open pores or does it already have a smooth skin?
    I think that what you are looking for is some kind of easy-flowing resin that seeps into the pores and then hardens. If it is already skinned, then you would have to build a hard shell on the surface or recast it (if allowed to).

    Have you tried spray Plasti-dip? I would try it on a sacrifice piece first (i.e. a nerf football if nothing else) to make sure it doesn't attack the foam. It's flexible in a thin layer but will stiffen up when applied in multiple layers. It's what all the Batman guys use after gluing the latex castings to their undersuits.

    If you are allowed to make a mold of this piece
    I say make a silicone mold and cast it in resin with
    a fiber glass backing

    Hi,
    Dig or cut out the back of the foam section by section and apply resin to the back side untill it is fully supported, then apply a fiberglass layer. Adding resin to the out side would just cover the detail.

    Hope this helps,
