Over the years the paint on the edge of the wiper arms have been worn away by the wind. I assume this is a common issue. I had the same issue with my old S10.
I could just leave it but I would like to repaint it. Has anybody else done this? What would you recommend I do. Should I prime the bare metal? Or should I just lightly sand and spray with a satin black. What has your experience been like, so I don't make the same mistakes
