First - what are these things called? I think the "door sills" are the part above the part I'm talking about below made of in Carbon Fiber (this is not a picture of my Roadster, BTW). Any recommendations on how I can get this (the stainless part) to look better? I spent a couple hours polishing #1190 to a lustrous shine and I don't want to just take stainless polish (unless you guys recommend that). I read an extensive review on how to detail a Roadster and they didn't seem to point out this critical component (maybe b/c I don't know the proper thing to call it). Any ideas?
