This year I wanted to make my own Proton Pack.  It is actually a project that I have been working on from the first time i watched the move as a little kid.  Back then it was lego built and trying to get it looking kinda right. 

Unfortunately I did not think of taking pictures until I was halfway through the build, but I would be happy to answer any questions that I can.

The whole thing is made primarily of insulation foam that comes from the big hardware stores for about $15 a sheet, and foam/poster presentation board.  I used polyurethane to keep the spray on primer from eating the foam, and once sanded it has a nice worn out look to it. 

Each piece was cut from layers of the insulation foam and then stacked and glued together.  At first I used plain Elmer's glue to keep everything together with three inch push pins to keep the layers aligned.  I found that hot glue worked just as well, but did not take one to three hours to dry.  

Any holes or gaps in the layers was filled with light wall putty which has the consistency of cake frosting.  Once that dried, I sanded everything smooth and then applied a layer of polyurethane.  Each layer of polyurethane got a once over with 320 grit to smooth it, and then another layer of polyurethane.  Each piece got between two and five coats.  The polyurethane drys to an almost plastic consistency and each layer makes the piece stronger.

That's awesome, I love it!

It's funny that you mention the styrofoam/spraypaint reaction.  I had a piece I'd carved way back when I was building my pack that I hit with spraypaint and it absolutely dissolved.  After that I stuck more to cardboard and tape instead!
