I bit down on my apprehension and went into SuperCheap yesterday to get paint for the spoilers. I wandered up to the paint matching computer and entered the code MAD as it appears on Firty's plate. Despite books and websites not listing it or identifying it as something other than Hyper Silver Metallic, there it was on tne screen.
The guy mixing the paint up for me said the database of colour mixing formulae was created by the same man who painted Australia's golden carriage gift to the Queen - I suppose that makes him an expert.
I walked out with a can of Hyper Silver Metallic and another of clear acrylic. Tomorrow is another day off work and when the first coat goes on.
