Only partly on topic

I've got a project I'm building that I would like a little feedback on.
I'm building a scale model M1117 Guardian military vehicle. Although if I
build it properly it won't fly, I'm planning on using some composite
techniques that you guys are familiar with.

I have built a steel frame that will act as a role cage. My intentions were
to glue foam to the frame, then glass over the outside and inside. I haven't
actually worked with fiberglass before, so I could use some pointers. My
first question is weather there is a better core material than foam for my
application. I understand that foam has some heat issues that require white
paint. Obviously I would rather a nice pretty camo pattern. I'm not as
concerned with weight as I am strength, but I do need to keep it lighter
than 1/2 plywood. The body panels need to withstand multiple paintball hits,
and an occasional tree branch. My next concern is the possibility of my
steel cage causing the fiberglass to delaminate since it would be on the
inside of my composite.

Any suggestions from the experts?

My understanding is that in non-structural applications, this isn't such
a big deal. The high heat from dark painted surfaces in direct sunlight
can cause shrinkage of the foam core. In a wing or canard, this can be a
"VERY BAD THING" (TM).. but in a non-structural mockup, where the only
thing it has to resist is raindrops and paintballs, I wouldnt get too
excited over "core" shrinkage.

You could even do it over a light plywood or fiberboard core. Again,
this is for non-structural applications.
