Last week I ordered some Permatex silicone to seal up the gap around the lower vent on my small. The aim was to see if it would cool down faster, and burn through less charcoal while cooling down. I promised to report back after some discussion in this thread.
I applied the silicone around the lower vent and let it cure for a few hours. I should have let it cure overnight, but I had dinner to cook. I figured I would also try out another mod - the foil rope/inside gasket mod as proposed by Grandpa's Grub a few years ago. It did light up and come to temp much faster than it had before. Hit 325-350°F in about 20mins. Cooked up some pork ribeyes and asparagus. Once dinner was done, I closed off the lower vent and put some foil on the top vent, before placing the ceramic damper on. The cool down did not take as long as before, but still took longer than my large egg does to cool down from a similar temp. When I checked the next morning, I had much more lump left over than I would have previously. So i think the silicone around the vent made a difference.
I will probably replace the gasket on the small with Nomex at some point, and will order some extra to apply around the top vent. That should make the ceramic cap fit more snugly to extinguish the coals quicker.
These are just my musings, so I would welcome any thoughts or suggestions from others.
