I have a bad paint chip on the passenger side headlight wash cover which I want to get repainted. I appears that it was replaced before but it was never primed before painting as it has a glossy black background under the paint, hence the big chip of paint removed from the cover. Any idea how to remove it so I can get it painted properly?

Also I have a annoying rattle coming from the passenger side air vent when I turn on the AC AC from cold. I'd like to remove it to investigate and if possible fix it. Any advice on removing the vent?

Thanks
