I saw a repeat of Wheeler Dealers on Quest last week during which the 'renovators' used electric (or air?) sanders to rub down the bodywork of a Corvette Stingray and then filled huge areas with filler paste which contained carbon fibre. Firstly I wonder if they damaged the body by not taking things easy and using hand tools - that aside, has anyone here used this substance and GRP paste to give a comparison? I can't imagine it's any better than GRP Paste (ie resin and 6mm copped strands), is it just hype? "Carbon MUST be better than glassfibre" doesn't convince me any! Maybe I'm getting cynical in my old age
