Hi,
I never did find a suitable colour for the 350Z to replicate le mans sunset orange. Whatever I tried just didn't look right.
In the end, I went and bought some plastic safe lacquer primer, both
grey and white, give a coat of grey and then white primer, and then
used dupli colour le mans orange. It's automotive paint, so it is hot
lacquer hence why I needed to use a good lacquer primer to seal the
plastic, to stop the automotive dupli colour melting the plastic, and
doing all kinda strange stuff.
you can see the result from here if you like -
