With the tank removed, the micro and urethane could be covered with cork. The cork serves to protect the tank from abrasion by the support materials. You can also see the strip of urethane applied to the top of the aluminum support for the tank ledge.

The top of the back rest removed. The rotary tool could not get into the area on the sides. A hacksaw blade was recruited for that effort. And it was an effort!

The white stuff you see is low-expansion foam that was squirted in to provide support so this wouldn't happen. Unfortunately, I could not get foam under the port side sufficiently to support that side. That's where the crack developed.

Here I have annotated the important elements. The red outlines the fiberglass support bonded to the bottom of the tank. Blue arrow points to the blue crack. The crack formed exactly as a stress analysis says it should, at 45ยบ to the corner of that supp

It was determined that a 1/4 in (6.4 mm) thick piece of rigid urethane foam topped with cork was needed to support the front "ledge" of the tank so it wouldn't sag.
