advice on re-core fuel cell hatch

[phatdaddy]

I did ridge, i had 6 five gallon buckets full of water, plus a couple of of battery cores and 100 lbs do lead ingots on it. I applied a thickened mixture of cabosil and epoxy on the hatch, wet out the ply and put it on the floor. Then stacked the weight on. Worked great. After that, a layer of 6oz cloth.

Solid as the deck of the kitty hawk now.

Exactly skunk. I was thinking about doing the squares again, but figured this was faster.

Worst part of the whole deal is my caulking.
