Mold was fun to build. We noticed the manual calls for the boxes not to be left flat. I think it said something about humidity and warping from being on the ground.
Installed bulkhead, hatch stiffener, and galley hatch trim. Tried to make it plumb. Later when I installed galley flat, 1/16” was removed along this trim so the flat could fit inside of it.
After 1st epoxy coat it looked like sandpaper. Waited 24 hours and sanded with 80 grit and applied 2nd coat. I’m guessing it soaks in at first and tops it off the 2nd time.
