Aluminium under the bonnet
I was told that it was tricky to get an authentic aluminium look under the bonnet. This was because there is a theory that the alloy will contract and expand at a different ration to fibreglass. Therefore, if the 2 are bonded together there is a great risk of one of the components giving way. I met with Mike and John Heather who have built a Cobra replica and did exactly this. mike tells me that he has had no trouble whatsoever. So I guess it is possible. The pictures below show the bonded finish on Mike's car. I met him at the Cranleigh Classic Festival, August 2017.
