Gases passing through pulled rivets

I concur. When the vents are closed on the Onex the wind from the tail is blowing around the seat. It is more noticeable in the winter time. When I open the RV vents the draft from the rear is almost gone.

This is great information from a couple of people who have flying aircraft. I will definitely take care of sealing the back end. Thanks.

Anybody ever figure out a way to seal the ruddervator pushrod exits on a Waiex?

The flat bottom of the fuselage, straight sides and curved top on the Sonex are similar to my Bonanza/Debonair, and the aft fuselage pressurizes in flight, making the cabin hard to head in cold weather due to air flowing into the cabin from the aft fuselage. The Bonanza/Debonair airplanes apparently have long enough tail pipes so the CO does not enter the cabin from this issue. I never have any exhaust residue on the bottom of the fuselage. How far below the fuselage do your tail pipes extend? Just a thought here.
