Grey chassis v white chassis

[GBinUSA]

So I'm seeing a pattern, in the US cars anyway. 1985 and older cars all appear to have a grey powder coating. 1986 -1987 all seem to have a white powder coating. The grey stands up well to the passing of time, whilst the white finished ones don't. Does the white finished chassis denoted when a TVR started doing the powder coating in-house?.

Having just re-read this thread.....I'm going to make the assumption that a white powdered coated chassis will tell a more telling story of the chassis condition than a grey one. Currently looking at an 86 car with a white chassis.
