I decided to repair that damaged door and centre section, so thought that drilling holes and pumping in filler would be best.
The door was the worst which had a large crack through it, the roof only a small crack.
Well too cut a long story short that did not work and I resulted in cutting out a panel, making a good bonding surface and inserting fibreglass matting in the area between the two panels.
The end result was a solid repair but will need finishing later before paint.
I also trial fitted the canard wings, dive planes call them what you will.
