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.

Here the urethane on the aluminum ledge has also been covered with cork. The cork both served to protect the tank and the urethane.
