I agree - flash chromed
That magazine ad is most likely done by an artist just like the 70 Z28 brochure. ^
You would think by an artist that is under contract to do a true rendering of the subject.
I would agree. But is the ad stuff like a special first car sort of thing or is it a true representation?
Surely, someone has a good color photo closeup from 1970?
70 Z28 put away in 1977. http://www.superchevy.com/features/1701-barn-find-rare-1970-camaro#/

This one has a lot of salty road life. And a sunny picture would have been nice.
This one's trim rings look like mine did after 18 months from the factory.
Neither really answers the question; calling on Shirley, certainly SOMEONE HERE has a good color photo of the wheel from 1970?
Charley's 1100 mi LA Z28 he used to own. A 1970 SLR film camera isn't going to get a real good photo and if they did, it won't be of a tire and rim. It'll be of the complete car. We weren't into that in 1970.
Another of Charley's old car:
An NOS 1st design ring on eBay:
So what is it? Bright chrome or subdued brush look?
I can see the brushing on the trim rings above.
Chromium's Effect on Surface Finish
Chromium duplicates the machined surface finish up to 0.002 thick(decorative chrome is .0002 -.0005) and thereafter a progressive increase in microinch finish is detectable with any increase in thickness of plating (if the brushing is deeper. This condition is slightly exaggerated on shot-peened, brushed, or blasted finishes.
Chromium never "levels off" or "fills in" surface imperfections. Defects, such as pits, cracks, or scratches are amplified, and if a highly polished surface is desired the surface should be highly polished before plating.
Light, corrosive atmosphere 0.0002-0.0005 thick
Most wear applications 0.0007-0.0015 thick
