Not sure just how I'd have "sloshed" these tanks, one in each wing.
I glassed the bottom panel, allowed to cure, then attached with a
resin rich flox bead on all surfaces. The bottom foam panel was
then installed and sanded to shape and glassed.

Sloshing fuel tanks typically means putting some slosh compound in the
tank, then, as in the case of my KR, position the wing so as to allow
the compound to run along a seam to seal it, then move the wing to run
it down the next seam, etc until all the seams have a thin coating to
seal any weeps.

I'm not sure how anyone could close up a tank like mine and fill it with
a liquid, even as viscus as water, and know it covered all the necessary
parts of the tank. My odds would be better at shooting turkeys in the dark.
Question: What material are the tens of thousands of Cessna and Piper
tanks constructed with, aluminum or steel. What keep them from leaking?
If aluminum tanks fail at the welded seams, why not construct the tank
to the point of all sides finished except the top with external welded
seams, run an additional bead on the inside of the seams, then rivet the
top to flat seam covered with Pro-seal and weld the seam externally.
Except for abrasion or puncture what could ever fail?
Tip: to help find a leak in the tank use a piece of plastic hose, 3/8"
to 1/2" diameter about 24" or so long, hold one end to your ear and scan
the tank with the other end. If you get anywhere close to the leak
you'll hear it. I found my leak in a mater of minutes. A resin rich
layup, squeegeed to fill all pinholes, and possibly an additional coat
of resin brushed on, is much easier than cutting the tank open to
repair leaks or slosh a tank with, basically, your eyes closed.
Whichever method / material you chose, do it right or do it over.........
