	For any areas of significant fibreglass loss (such as the front "chin" spoilers and some jacking damage to my nearside sill) it may be worth strengthening the repair with strips of aluminium +/- aluminium mesh, worked in between layers of matting. These strips of aluminium (about 1" wide) should be bent to shape, and then screwed into place (clamping wet matting before it sets) using countersunk screws in from the outside of the clam. The screw heads can then be completely covered with resin from the outside, leaving them invisible once filled and painted.
