Ihave used the special carbon impregnated heat converting RF absorbing rough
surface foam rubber made to do the job. At the time it cost 20$ per sq ft, I
bet it now costs twice that. The promo from the advertising suggests it is
made by Clark Kent on his home planet. It isn't worth the cost, and it has a
short life span. The foam rubber made for packing with a grey color, not
white, is far better and dosent degrade with UV light.
