Hank, they are trying to keep the cig smoke out, not make their own!

I've seen electrical outlet "foams" for sale.

I'd also still be looking for a way to make your side positive pressure.
Perhaps a cold air intake for the return side of your furnace.

The outlets--that's something to try (though I wouldn't think that much
air would pass through them.
Nitrous might help. ;-)
