I was struggling repairing all the cracks in the car roof as the fibre glass was that thin it was causing it to flex with the smallest amount of pressure applied which made sanding the roof almost impossible. Took the radicle solution of stripping the car down and filliping it upside down to put a couple of layers of GRP on the inside of the roof. Hopefully my father will return tomorrow to give me a hand to flip it back over and refit front end and bonnet.
