Default Best Practices for Bonding Foam Bulkhead?

So Iíve been rebuilding this 23 Seacraft and Iíve chosen some new material (foam) to work with for creating this fish box. To date Iíve been using Coosa for the transom and bulkheads but I wanted to use this structural foam here for better insulation.

My question:
Should I bond the raw cut edge of the foam directly to the hull with thickened epoxy and then fillet and tab as normal or do I need to add some glass over the raw cut edge before bonding in place?
Same goes for the exposed edge that the deck will sit on. Does that need to be glassed to get a good bond to the deck or will I be fine to glue it down with thickened epoxy as I plan to do everywhere else?

My gut says just glue it in and proceed as normal.

I donít recall what the manufacturer and spec is on the foam but itís pretty strong stuff as foam goes.

FWIW- Iím planning on adding a couple layers of 1700 over each side before glueing the panel in place.
