Roof Rubbing Or Stone Chip

Hi everyone,

I have a 2025 MX5 RF ND and a while back I noticed what I took for a stone chip on the roof. However, I’m convinced it’s getting worse.

Today, after a trip to the coast with the hood down (rare opportunity), I noticed that it’s worn through the paint and so I’m now wondering if it’s the roof rubbing when stowed away.

I’ve attached some pictures (not sure it helps).

Does anyone have any thoughts on this? I’ve searched the web and issues with rubbing seem to be scratches.

Thanks for any / all advice.
