To Vent or not to vent. That is the question.

and,how did you prep in the inside of the hull,before you "unrolled the matting" ?

Didn't do it and don't plan on doing it (based on this thread).

But I would take the sandpaper off the sander and do it by hand. I think epoxy would stick pretty well. Mine has a pretty rough surface in there, so I think you don't need to prep the inside surface of the hull too much beyond getting it clean and solvent free.

Also I suggested using 6 or 10oz cloth. Matt is probably too thick for this step.

This is my picture, but it's crappy so worth much less than 1000 words... the red part is much smaller than what I would actually use, and I am only showing one of 4 sides:
