One thing I have noticed for a long time is that some pilots sit on their
wing tanks on the ground while talking with other pilots. i.e AirVenture.
It seems to me that this torgues the tank downward and may contribute to
leaks.

I would never sit on the fuel tank. It=99s .032 instead of the .024 fu
rther out. But it was never engineered for a compression load. The most weig
ht I set on the wing are some light tools and parts padded by 2 layers of to
wels.

My experience from owning a Mooney for 18 years before the RV build: The
version of sealant used 50 years ago is very different from what Vans
specifies and supplies.
With current Pro-seal or other brand mil-spec equivalent, shocks are very
unlikely to cause a leak. If you have ever had to remove the stuff, you
will know what I mean.
On the other hand, if the skin isn't perfectly clean, as in no
fingerprints, no other contaminants; the adhesion can be imperfect. Vans
only specifies and uses in the quick build wings the B-2 compound. Mooney
on the other hand specifies a layer of B-2, a layer of A-2, and a sealer on
top of that. I've seen leaks in relatively new Mooneys, even with those
extra layers.. I fully stripped and cleaned a Mooney tank (a nasty job) and
resealed it. After 9 years and several hundred hours it was leak free. One
of the tough requirements of any of the Pro-seal compounds is the number 2
means it is supposed to have a 2 hour pot life at 75 degrees. IMHO, you
will be lucky to go 1 hour before it starts getting tacky and doesn't want
to spread smoothly. While I used cartridges and a pneumatic gun on the
Mooney, with the RV, I would mix only enough to cover what you can rivet in
30 min, then make a new batch. After application let it cure minimum 2 days
and preferably double that.
Mooney main gear is attached directly to the wing spar that serves as the
back of the fuel tank. Doesn't matter how hard you land, if it doesn't
damage the gear, it won't cause the tank to leak either. That wasn't true
with the 50 year old gunk that got hard, dry and brittle. The current
Proseal does not harden beyond the initial cure. It stays flexible, and it
takes a lot of force to make it separate.
So either there were contaminants on the skins going together, or a gap in
the sealant as it was applied. Personally I would use B-2 followed by a
brush coat of either A-2 or thinned B-2 spread at least an inch beyond the
B-2. The quick build wings have way too much sealant at the end ribs, I
guess to make it look smoother and to try to prevent any damage to the
sealant.
