Thermal coatings improvement of cooling capacity of a Nickies cylinder is questionable, since we already acid etch all surfaces to maximize surface area. A coating would impede and more than likely reduce surface area. Cyro'ing is also questionable, since our aluminum is cold worked to a T9 spec through the extrusion process, pressed through a die at nearly 20 tons of force.
