In the sense of BBQing
this is insulating.
Not to say powder coat isn't used to insulate it.
On the flip of the coin too, can you prove that its the powder coat that insulates it and makes the temps so rock steady?? That is what you originally posted was it not? I simply gave you feedback saying, and sorry for not clarifying that it was my opinion and not fact, that in the sense of BBQing, powder coat may not be insulating the PBC, or since you corrected me, may not be doing it well. I was saying that there are other factors to consider whether they be factually supportable or not. That is the jist of what I was
trying to get at. I guess I failed.
