I have the "Wheel Vintiques" 15" repops on mine and the chrome is flawless. Far, far superior to the chrome on my originals were even the day the car came home from the dealership.
I put these repops on nearly 20 years ago and they look perfect today: no rust, no flaking or hazed chrome...nothing.
Now, the repops are NOT 100% accurate: The shape of the rim is a little different, and the spokes are shiny chrome, like the rim is...not a "brushed" finish like the originals.
Not a big deal if concours originality is not your goal. Only an MCA judge or a fanatical enthusiast would ever know or even see the difference.
These chrome on my original Magnums never looked as good as these repops...even when new. It was always a little "hazy", and there were even quite-visible inch-wide bands of discoloration where it looked like a clamp or something may have attached when the rims were dipped. This was on all four rims.
The "WV" rims have excellent "show chrome" sparkle and flawless shine. I like them much better than my originals.
Same story with my rear bumper: the OEM had rather substandard, slightly "hazy", or a white-ish appearance to the chrome. I was going to buy a new repop many years ago, but the repop bumpers back then were not correctly shaped on the ends, so I had my original "show chromed" instead. It came out awesome...the difference between it and OEM is night and day, no comparison.
Not sure if the latest bumpers have become more accurate...mine still looks perfect so I have not bothered to check.
