got the coring all dry fitted , it took 7 4'x4' sheets to cut and fit everything with enough left over to do the hatches. I put corelite down where the console and leaning post will be mounted.
after everything is dry fitted, I mark everything to make it easy to reinstall after the I apply the divelette putty.
I ran out of putty and have to get more tomorrow. I got the back half of the boat all puttied into place.
