I am replacing gaskets on a leaky MTH smoke unit (both the circuit board and pot to fan housing) and was wondering if people have been installing them "dry" (gasket only) or adding a little RTV or other adhesive type material to get a better seal?  See attached photo of gaskets.  Thanks!IMG_4414

Thanks, I put the blue circuit board one in dry and added a thin layer of RTV on both sides of the pot to fan unit one (red) since it was pretty stiff and figured it might not seal without a little help.  The old MTH one was more of a foam material for the pot gasket.  I'm letting it dry and I'll report the results.
