Any other Ideas would be awesome. keep em commin!
Just thinking aloud again...
What if you used wax paper/saran wrap/etc to protect your styrofoam during the fiberglassing, and then after it's cured and you've melted the styrofoam out, you could cut your tank in half. Then it would be easy to extract the wax paper/saran wrap, and you'd also be able to fully visualize your tank sealant coating all the interior surfaces.
When this is done, you could just fiberglass the two halves back together? And then slosh a little more tank sealant around in there to make sure the gap is coated on the inside?
