Remove Foam Spacers
Remove the foam spacers that were originally used to keep the hull from collapsing.
You also need to remove the foam and glass at the front of the bow. I used a chizel to break the glass and then a plasters knife to cut the remainder of the glass away. You also need to remove all the remaining glass with some sandpaper. You might want to use glove for this task as I took the skin of two knuckles before I worked it out.
