I must have had 2,500 pounds of aluminum hard (black) anodized. The facility demands clean parts, free of oxidation and there will be a per minimum charge and usually a 2-3 day wait. The thermal transfer (especially radiation) increase is impressive. If the finned plate is clamped to a cold plate, use Arctic Silver as a thermal paste to increase BTU transfer. This comes from very early experiences with Kool A Tron ice chests. Refrigerator manufacturers are turning out Thousand Dollar Garbage because there is no real competition. I bet the boys at Norcold golf with the Dometic crew.
