Seals for bottom vents?

[Stabbin-Wagon]

I have a Brinkman Gourmet Smoker that I've made some mods to. E.g. New therms at both rack levels, seals around the lid and bottom, top vent and 3 bottom vents. The vents are the round 4 holed weber replacements. They have been placed on the bottom of the charcoal pan, which is flat. They work but there is still air getting in around the vents due to the curve, as I suppose they are meant to be used on a dome. Any ideas as to how to seal these up some?

Can you take them off and gently pound them flat using either a rubber mallet or a block of wood.

I have as best as I could but there is still a slight convex/cave to it around the edges. Small though, maybe a millimeter or two.

Maybe just put a bead of high temp RTV around the lip of the vents. Once it dries up it may work.

Make holes and plug them with tin do plugs :cool:
