The steel cage, on the inside, won't get any hotter than the ambient
temp of the inside. It's not sitting in the sun, it's in the shade.
Desert cammo will be MUCH cooler than OD Green. But if you can
survive in the temperature on the inside, the resin will be happy.

If there is any softening of the resin (there won't be, but if there
were) it wont cause any delaminations, just softening, so you might
end up with a dent from a tree branch, etc. It would just add to the
realism.

You would not need the steel cage, unless you need it for rollover
protection, and if that is the case, just do the roll bar and support.
