SKOOL TELL ME IT CAN BE FIXED!!!!

So it's 110* and I've spent days grinding and prepping to install the new stringers and kleets I built and sealed with resin


right length hieght all this after spending hours cuting measuring and ripping ferring strips because the old floor had no pitch to it. In other words, it was angled towards the center allowing water to pool instead of running towards the walls and rear as it should.
I went to install the stringers to find that the previous owner installed a box. This box did not allow room for the new 3/4" plywood stringers to fit inside the space so I removed it.


This ment more grinding and prepping. So me and Nikki ( my trusty 4 1/2" angle grinder) went to work. Amist the cloud of dust I noticed something that didn't look quite right. Figured it out yet? As the dust settled I noticed two things.
First a nasty on my shin that Nikki put there

AND THIS!

I know it's from the outside but, that's because when I realized I had cut through the hull, I promptly ground down the clean glass inside and hopped out and under to sand away bottum paint and gel coat. It was then that I remembered, I have never fixed anything like this before but fugured it had to be ground/sanded down to bare material and packed and glassed and brought back up like any other hole.

I have no clue where to go from here, any suggestions.
Thanks, Mark
P.S. the stringer really are perfect and Stink was right, boatyard is good resin.
