Hi All, I am just about to complete purchasing an OE Sapphire Cosworth 4x4 heat shield which has sadly started to deteriorate at the section which sits above the exhaust. Is it possible to repair the damaged areas? I would really like to know what the shield is made out of...fibre glass, resin?? so that I can use material this to cover the affected areas, sand down and then repaint the whole shield....I will then use a reflective material to give the shield a better shot at survival! Is anybody able to shed any light or has had experience of doing the same? Thanks very much in advance
