Problem solved - chrome paint! (It does exist but don't ask the price :-)
I'll search for that blue in brighter light. I did some tracking shots of one of those 427s on a very bright sunny day but that was in my pre-digital era so it was on (sigh) film.
Tim: if you email me (tlegate@btinternet.com) I'll send you an image of an FIA car with very dark blue paintwork and NO stripes. I shot it on a very nasty dark day just before the light went but it still looked seriously fantastic!!!! I need to own that car very badly....
Trevor,
Sent an email ... thanks for looking!
As far as the chrome paint goes ... I'll leave that to RodKnock and the Krikham / Aluminum CSX guys.
