I swear I searched the nsx board (nsxprime.com) last week but found little info on polishing the factory wheels. So this weekend I took it on myself to learn on the job with my own wheels and I'm pretty pleased with the result. Anyway, then today I search nsxprime again and find pictures of wheels like mine that were professionally polished and holy shit they look great.
I definitely am going to look for a buffing wheel to use and work mine some more. I have some room for improvement, especially in the inner areas between the spokes.
One of the wheels I found searching today.
