If i may add,

In addition to the wing saddle tape, i also take aquarium silicone and squeeze it into all the openings, "ie", the gaps where the rear landing gear struts exit the fuse, and the big hole in the firewall where the steering rod passes in the land setup, i also run a beed all the way around the firewall. The big hole in the firewall is where 90% of the water gets in, in a dunking.

Between my Dad and i, we have dunked our Cessnas and my Ready dozens of times, and with the silicone in all the gaps and the saddle tape in place, they stay completely dry inside.

We leave the tail open where the elevator pushrod exits, because if a small amount were to get inside, it would "auto bilge" out the back in flight anyways
