Bill57- Be sure to get multiple coats on there, with a wait time between coats, to ensure it lasts long enough. I do three/four and then wash with sorta-strong shampoo mix (not Wheel Cleaner). I sure hope it works as well for you as it does for me!
In my experience wheel rims that go through many years of Upper Midwest Wisconsin winters WILL succumb to corrosion eventually...
Not, IME, if maintained to any decent extent. That has simply never been a problem for me and some of our winter drivers have been used in salt/etc. for a long, long time. The winter wheels for the Tahoe oughta be *AWFUL* by now, but nope..just all scratched up from before I got `em, and I don`t even LSP those. It seems to be a matter of whether the wheels` finish gets compromised enough for the salt/etc. to reach the underlying metal, and/or whether the salt is allowed to stay on them long enough to get working in the microfissures/pores of the finish, whatever that happens to be. Quickie wheels/tires-only cleaning can apparently go a long ways as I`m sure not all that Autopian about such stuff.
BUT...also just IME and of course YMMV...the centercaps are a different story, especially if you pop `em out of the wheels (in my case so I can hang the wheels up). The finish on the edges gets compromised and then there`s simply no stopping the corrosion, best you can do is try to slow it down until the time comes for replacements (the availability of which is something to consider when buying wheels). The centercaps for the A8`s Borbets are getting pretty nasty (by Autopian/my standards) even though the wheels themselves are still OK despite being used every winter since `00.
Speaking of powder coating on rims, does anyone know if ANY vehicle manufactures powder coats OEM rims in production??
I thought that most all oe wheels are powdercoated these days. The ones on my `01 Mazda MPV gave every indication of that, just prepping them for refinishing (after they got damaged by others...grrr..) was a huge PIA as the stuff was hard as a rock.
Ron Ketcham oughta know...hope he checks back to this thread and gives us the straight scoop.
