(i.e., Cut the access holes first and then glass or wait until after you glass?) Thanks, Jim

After glueing in the wood and laying the mat, I cut the hole. I still had some grinding, sanding, and glassing to do after that, so that was when I hit the inside edges of the holecuts with resin. You could also cut the holes after glueing to the top, before laying the mat. I think either way would work fine.

I did mine just like Awthacker did his....my first fiberglass job too....came out well. You can seal the edeges of the hole after you cut them. I woulld think you wouldnt want to mess with lining them up while you are trying to set the two pieces together....

The only other tip I got from here (I think it was ridgerunner) was to put plastic under the holes in your hatch skin because if you get some resin to squeeze out around the hole you could glue your new core to your work surface.
