The 300M wheels are actually A-Mold and the wheels are made in Mason Ohio and shipped to Kitchner for plating. This is the new plating I was discussing.
This company also supplies GM with their shiney chrome wheels.
Have a couple of boxes of cut up wheels they have sent us for testing of cleaners.
They are senstive, to acids and alkaline cleaners.
Our Custom Wheel is the only one that has passed the test they speced. This product, the Custom Wheel, has been in use by Chrysler Canada for 4 years, under the Master Prep DCX label. No reports in 4 years of damage to the coating (just don't put it on a hot wheel)
We are presently in testing with Superior Industries on the same product. Superior is the main supplier for Ford Motor's bright chrome wheels.
We supply this wheel cleaner to Saturn and Saab under their label as well for consumer sales.
So far, we have passed all tests by Superior, with flying colors, no damage.
So, I guess we know a bit about the wheels.
Keep a good coating of a polymer sealant on them, don't let the carwash or detail guys spray them with hydrofluric acid cleaners, don't use Simple Green or the Castrol product on them. Be careful of using any product that you are not familar with. High or low pH products, those with sodium hydoxide, TSP, butyl's, etc will attack the coating.
They will be fine, just make sure you don't ever hit these wheels with anything but water if they are even warm to the touch. The chrome coating is a Japanese patented process,and is less than 1/20th of mil thick. When it is violated you will see an "orangish" tint to the area.
