    I use foam coat from http://hotwirefoamfactory.com. You can add chemistry to strengthen and/or rubberize it.

    How long does it need to last?

    If it's only temporary, get some GOOD exterior latex primer, I suggest Bulls Eye 1-2-3 by Zinsser.

    Give the foam an initial coat with just the primer to seal it down, and provide 'bite' for the next layer... Next pour some of the primer out into a bucket and mix in some pre-mixed spackling compound the amount you mix in will be determined by how much detail you need to preserve in the final piece, I would start with a small batch of 50/50 and go from there, if you use a small roller to apply you can get a nice uniform slightly bumpy surface... The spackle will make the paint much harder so you will get a hard shell on the foam... Now you can primer it again or go right to the final paint and coating from that point, make sure you seal down the primer/spackle coat with another coat of paint so water doesn't leach into any exposed plaster on the surface...

    This is only for a temp display, not one that is expected to last for long in rain and humidity...

    It's supposed to be outside . All the time. On the side of
    A business . They bought the shapes but didn't have them
    Finished. So I get the fun. No detail just silhouettes

    I am with Exoray on the latex based paint. I would imagine some water-proofing paint they use on exterior sheet rock to seal it would work nicely.

    If it's for full time outside then, the best option is an EPOXY (not polyester) based fiberglass skin, or a resin based foam sealer (can't recommend any of them off hand)...

    If you want or don't mind the look of stone, you can use portland cement, some fine sand and burlap, basically doing a fiberglass like skin with cement/burlap vs resin/fiberglass...

    You can try this stuff Steve's Coating for Styrofoam

    And you could go with polyester based fiberglass but you will need to prime the foam real well as the styrene in the polyester will vaporize the foam...

    Use Elmer's glue to coat it, that's how I coated my kids playroom television tree and it worked great for my Han in Carbonite. A few coats of that will be great. I have a new found respect for Elmer's glue!

    Just make sure you seal it with exterior paint, generic white PVA glue is not weather or even water resistant, but it will make a good base coat...
