My bike has this side plate mount and it originally had a reflector on it which the previous owner removed. But I kind of want to cut the extra metal tab off and paint it to prevent rust. I don’t want it to look hack. I’d want a clean cut so after it’s painted it looks like it was always that way. I don’t know the best way to tackle this and don’t want to attempt something and regret doing it. Is this worth it or should I leave it? How would you do it? Thanks
