So I bought a pipe off ebay that said it had been sanitized and refinished. I liked the look and bought it. So the pipe arrived and looked good. It had just a light coating of cake inside the bowl. No issues that I noticed and have been smoking it for a year or so. Well the pipe ghosted on me and I decided to due a salt/everclear treatment and ream it out to get rid of it. Well what I found was there was some pipe mud under the cake on one side of the bowl. Now it looks like it was done to fill in a crack and it was done well. Was just wondering if the seller knew about it, should it have been disclosed or is repairing a crack inside a bowl just a normal part of refurbishing a pipe?
