Yes when properly torqued it will remove some paint. When you swap cogs you get all those nice circles . Just the way it is, shows you use the bike which in itself is a good look.

Some frames have the paint strategically missing from the dropout area. I like the idea, just never had a frame that came this way. Can't think of a way to cleanly remove said paint to replicate the look. Maybe use a steel dropout insert from an aluminum frame to make a reverse template and sand it off.
