@swamprb The finish is porcelain coated just like all the weber kettles and Smokey Mountains
I'm concerned about using the One Touch system on this setup. The lower vents of a true WSM bowl are obviously mounted higher up on the sides of the bowl itself. No way that ash would ever build up that high...even during an overnight cook. I worry that during longer cooks, I'm going to have to be more conscious of the ash clogging up the vents because they are oriented so much lower in the bowl. I'm not sure I want to sweep them back and forth to clear the vents...and in the process send a cloud of ash up towards the food.
