Gary - Yes, the cardboard currently represents the finished surface, which will be a layer of filler.
So the fibreglass "off cuts" will be 'glassed into place
inside the hump, with filler added to give a smooth finish , level with the edges.
I only had a brief look today, but this is going to be a bid harder to do than it sounds.
So I may look at fixing some mesh inside the hump and then using the chopped matting / resin mix I used to "bulk out" the scuttle as an alternative.
As you can tell, I am making this up as I go along.
Cheers, Paul.
