Got the front section of the floor leveled. I used the sheet of 3/4" MDO
crezon
cut into 3" strips. A 4x8 sheet is just enough material to cover the stringer tops with 2 strips (which raises the floor 1.5" + 1/4" of epoxy puddy/glass). I was very impressed . . . the MDO had a only few small voids in the entire sheet.
I still have to level the back 7ft of the boat, round the sharp edges, and add 2 layers of 1808 over the tops of the stringers.
The make shift floor is a bunch of mdf scraps.
