FISHY - you pulled a D lens apart, was the front element sealed??
I doubt the lens is sealed other than by whatever contact force is present between the outer lens and barrel. BUT, I do think the balloon method might give some minimal water-proofing for a shallow submerging if the camera were first wrapped (front to back) with very clear
plastic film sandwich wrap, pulled tight so no wrinkles but not so tight as to deform the plastic film. I've done this on water planes just for camera splash protection, and cannot tell the plastic film is there. And then if possible, add the balloon without causing the plastic film to crease or release.
It wasn't mentioned how the balloon is best installed, e.g. do you roll back the small "lip" end of the balloon until it reaches the aft end, then stretch the whole thing over the butt end of the camera and roll the lip end back over the camera to the lens?
