Jason- I am only familiar with Lexus wheels, but all the chrome Lexus wheels I have seen are chromed the same way, with only the visible areas chromed, since the chroming process is so labor intensive and expensive. I am checking with my buds on
www.ClubLexus.com to verify this, and so far they concur.
Being unfinished, the insides of the wheels had so much accumulated road grime/brake dust that the only way to remove it was something very abrasive. I am certain the only thing I removed was a lot of dirt.
Andrew- Is this the Duplicolor how-to?

How has yours held up?
I like the color of the surface I have now exposed so I wonder if I can skip the silver paint step and just go directly to spraying the raw alloy surface with the Duplicolor WP103 High Performance Clear Spray and be done with it!
