I’m going to email the maker as well as the place of purchase. Good advice.I've had no problem with either my Petersons nor Johs, but this is not a minor defect. No one wants to settle down to a pleasant smoke and end up with their hands and maybe their clothes covered with residue. It shouldn't matter if the pipe is over heated or if the weather is hot. Apparently this is a problem in pipe finishing when it is done too quickly or with mis-application of the stain.
I can understand not wanting to get into a quality control discussion with the maker, but you'd be doing the pipe maker and potential customers a favor. I'd contact them with this picture and full details about the pipe, and see what happens. Otherwise, you probably have to refinish it at your own cost and expense of time.
