as always, Bud's insights are great!
that said, FWIW, my classic's gear slot is absolutely, definitely negative
pressure wrt to the cabin, proved by repeated tests with paper and fabric
getting sucked onto the slots.
I believe most of the ingress of any exhaust in my ship is through the flap
drive slots, when they are extended.
Cheers,
Pete
