I've read where some folks are using closed cell foam and other Styrofoam
types on the outside of their refrigerators and freezers to boost insulating
values.  Is this practical in a very humid environment like the deep South?
This house gets wet in the summer.  Anything made of leather will turn green
from the mold.  But will the insulation hurt the appliance, i.e. water
condensation between the unit and the insulation?  Or if the insulation is
well placed, no condensation........

A friend of mine used spray adhesive for his when he did it. No he was never
planning on removing the foam

Seems to me the painted steel outdoor fridge skin would be OK, with a layer
of foamboard all over, well-sealed to the skin with silicone caulk. Any bits
of exposed skin might have an extra layer of rustproof paint or polyurethane
varnish for rust protection, since it will be colder than usual.

Many fridges have cooling radiators in various places behind the metal, as
well as exposed on the back.
Insualting over one of these hidden radiators will effect performance,
sometimes greatly.

 I  insulated a new Sears unit  the coil on that unit are all underneath.
Yes insulation helps alot usualy R  10 - 15 is enough extra.
