Wondering if anyone else has seen this. I washed the 2019 C2S today (10k mi) and when I raised the spoiler, I saw this “wear” on top circled in red. It’s not calcium buildup. It is some sort of discoloration. Looking under the spoiler I see no evidence of wear or impingement.

It looks worse in the picture granted but it is there. Thoughts?

Looks like the center of the spoiler, the least supported section, flexing in the airstream when it's down, rattling against the bumper cover and marring it with whatever grime is already there.

Those appear to be pits and scratching, not just discolouration. Does your fingernail catch on them?

Yes, it’s very light pitting. Notice the sharp edge. I think the spoiler is vibrating down on it. I can push it down a bit while in the closed position.
