I have an 03 I got in Dec of '02. I was washing this weekend and noticed that there was some tiny plastic peeling on the INFINITI sill plate edge, I pulled it and the entire plastic covering that protects the sill plate came off along with all the little scratches I thought were in the plate but were really just in the plastic covering. Now my sill plates look brand new again, NICE. Guess they missed taking that covering off at the dealer when they delivered my car.

 

I bought my '04 used last year, and I still have the plastic foil on them. I'm tempted to peel it off everytime I wash it, but it's still on. Enjoy your brand new looking sills.
