Next I cut some small pieces of the fibreglass sheet from the repair kit and worked these into place as best I could to fill the hole.

When I mixed up the resin and hardener, I added a small amount of green acrylic paint to try to match the board colour.
Turned out just 'ok' as it's pretty hit and miss, since you don't have too much time to stuff around adding more paint and I wasn't  really sure if the paint would react with the resin.

Started to drip/pour the resin into the hole and onto the new fibreglass matting. 
You need to press the resin down into the matting, so that it soaks in and removes any air bubbles.

I was also careful not to let any resin get into and block the through holes. I used an old resister to clear the holes if any did get in.

The last pic shows about halfway done pouring the resin.
