Actually I doubt it would even need that, it would probably come off with the sanding. I don't know it's story, but it looks like someone's primed a wheeltrim while this was still attached so has a very thin primer layer on the outside surface. It's intact, has all three prongs etc, but it's just something else in the ever expanding 'just in case' parts box lol! I'll upload a photo when I get time in case someone else is missing one.
