Not sure if any other fellow 10th gen Civic owners here have taken a good look at the belt molding on the tops of their doors lately but you may be surprised at what poor condition they are in. The rubber 'wiper' that contacts the glass is prone to deteriorating and falling apart. It's apparently a known issue. Mine were in terrible shape, with the rubber looking like jagged teeth and were sticky to the touch, leaving black residue on my fingers. I should have taken pictures before they were thrown out but I wasn't thinking.
New trim pieces are about $20 per door and replacing it is quite easy. No need to take the door panels apart or remove the mirror. These guys show how easy it is to do.
My only regret is that the first door I did, I didn't roll the trim out far enough and ended up breaking off the clip. No big deal since it was being replaced anyway but the plastic clip fell into the door and that bothers me a little. Oh well.
