you can find a hard shell spray at demand products, decent price. I've made the mistake of not using this product before on my buck and went the other route, which set me back 3 months. http://www.demandfoamcutting.com/coatings02.html |

be careful with the epoxy you use. Polystyrene can heat up underneath, and send air bubbles to the top, creating irregularities. You should have used polyurethane, it would have cost slightly more, but it would have allowed you to use different types of epoxy. Just a heads up, I suggest you go buy a piece of polystyrene, a few pieces actually, and coat a 1'x1' section with different epoxy's, to see how it reacts to it.
Good luck,
by the way, who milled your parts?

If your resin is true epoxy, it will not attack the polystyrene. I am not trying to imply anything with this statement, but many people class all resins as epoxy when in fact they are not. You have epoxy, polyester, polyvinyl, and many hybrids. I have coated foam made from extruded polystryene, and expanded polystryene with several different brands of epoxy resin with no ill effect. On the other hand, I have melted it with polyester resin, bondo, automotive primer that is solvent based and gasoline.
I agree to run a test, but if it is epoxy resin, I don't think you will have any problems.

I agree with Mike, epoxy don't damage the polysterene (extruded foam). Already tried that in the past and it worked OK.
