I just smoked my Peterson 606 harp for the first time today and it was great! When cleaning out the bowl, I noticed that the airflow hole had been drilled across the bottom of the pipe, and into the far side of the bowl. There is only about a millimeter hole in the bottom wall of the bowl, but I worry this could lead to burnout. Should I use pipe mud to cover it, or will it just naturally carbonized with the rest of the bowl? Thanks in advance for the responses, and I can upload pictures later if it helps!
