Yeah that's an easy repair
1 sand away out damaged fibreglass by about 3-4" more, and feather the edges
2 remove broken bits of wood and taper edges.
3 make sure inserts are located correctly and fill gaps from removed wood with Q cell
4 sand flat and apply 3-4 layers of cloth over repair.
5 sand flat ,flow coat for best Finnish and paint
Might sounds easy, but it's not.
There is not way to secure the inserts with no 'meat' to 'bite' in.
It is just the matter of time when it will be pulled out after above fix. Sorry. The cloth works on tension, not compression.
To get the insert to properly 'bite', the only option is to drill the board from the bottom unfortunately.
At least 3 hrs work initially, plus sanding and finishing next day or so, 2hrs.
Good luck.
Yeah it works fine, I've done it and got another years use out of a board before giving it away to someone else still going strong.
Without looking at the board it's hard to tell but I would not think drilling from the bottom would help because the wood you will be drilling into would be all broken up. The wood needs replacing, Of course you could route out a round hole in the board, make up a similar sized peice of Paulownia and replace it but that would be so much work, Instead just use Q cell and you don't touch the bottom .
It's also all about spreading the load and the edges of the wood need feathering out to stop stress points.
Q cell is easy as hard as the Paulownia wood it replaces and I would have thought better at resisting compression, but if you want extra strength I suppose you could always mix it up with some finely chopped glass as well.
The only step I missed out in my discripion is to cover two screws with release agent or Vaseline, and screw these into the inserts, this stops fibreglass resin getting into the thread and helps locate them.
