:thx for the info.You just need to make it coarse enough to scuff the chrome, not take it off completely. I think I started with 180 grit and finished it with 220. After you sand, just use a good primer and then whatever color coat you wish to make it. I used Krylon for my paint and finished it off with clear to help protect against the bugs.
