Thanks for the replys but the heat shield is the black one that sits over the top of the turbo, trouble is the end which sits near the exhaust has a tendancy to melt which is what has happened. I can't decide whether or not to cut out the rot, protect whats left of the underside or use a heat resistant resin and rebuild the damaged sections with new fibre glass...I'm just worried that if I do this the fibre glass might melt?!? -any body had any experience of doing this type of refurb?
