Tonight was relatively quick. Some sanding of the lumps and drips from last night's work, then flip the boat upright and work on the cockpit-floor side of the hole punched through the bottom. A little work with the grinder/DA on the edges, then cutting and feathering the edges of the patch, and it was ready to glue.
You can't see through the floor anymore!
The edges of the hole are faired out and ready for the patch.
After filling the void with a small chunk of DIVINYCELL the patch is glued over the top of the hole.
The wax-paper covered dowel on the right side is to help hold some epoxy in a void I found at the edge of the access-hole where epoxy apparently didn't flow down completely Tuesday.
