Now that I'm not looking at it in a state of despair and frustration

It is not as bad as I first thought.
I will use knead-it to keep me going through the holidays.
Sorry for all the questions but I'd rather gather info than charge off and make it worse

Should I pull the top layer of glass/divynyl off before filling with knead-it? It has been pushed in but is still firmly attached to the yellow foam (EPS?) underneath so my first thought is that I will just scruff it up with some 360 sandpaper and fill with knead-it.
The entire puncture would fit under a 50c piece and is 4mm at the deepest point so this brings me to the next question. Once the shops are open again should I dig the repair out and add a new layer of fibreglass? or, should I leave well enough alone?
All payments for advice will be made with beer
