Recently I picked up a lot of pipes on ebay. One of them was a medico (I think. F on stem) bulldog. The bowl was cracked. I pretty much used the reborn pipes method of repair. I used some of the reamed out cake to make the pipe mud and wood epoxy putty to fill the cracks. I didn't do the sour cream coating inside the bowl. Seems to me that would go rancid. The bowl is still rough but better then it was.
