Just curious... Is it possible to only coat the inside? Or coat both and then remove the coating from the outside? Seems only coating the inside would reduce the heat transferred "into" the metal and would retain the original ability of the metal to dissipate heat outward. If the goal was to reduce the heat radiated from the pipe, only coating the inside would (may) reduce the heat (temp) that the pipe has to radiate. i.e. Rather than coating the outside and holding the heat in the pipe, why not coat the inside and reduce the heat transferred into the pipe in the first place.
