Tank bungs and lid reinforcement

Used West System Gflex epoxy to install the tank bungs

Gflex is tough stuff and looks like it will be more than enough to hold bungs.
Here is a video of a Kayak sawed in half and stuck back together with Gflex

                             Ribs on inside of lid to stiffen it up.

  Added a couple vents to the marine plywood core so it can dry out if it ever gets wet.
