Now is the time to start working on the panels. I have started with the round head of the window that has been covered with two sheets of fibreglass - one inside and one outside. There has been a replacement with clear textured glass on the right and there is extensive breakage on the left. The central portion is in tact.
This image shows the glass dismantled and some of it has been taken to be put into the water for soaking. All the glass except the red flashed is relatively thick. But the red flashed glass is very thin - less than 2mm sometimes, but still intense in colour.
