Well,.. I finally got around to painting my front and rear badges. It was pretty easy. I removed the front badge, there's only a 10mm lock nut holding it on.
I thought about removing the rear badge for painting, but it looked like a total PITA. So, I just taped it off and cover the rear of the car with an old beach towel. It worked pretty well.
As far as prepping the badges, all I did was clean them with Isopropyl Alcohol. I thought about taking some 400 grit sandpaper to them, but decided against it. If I have any problems with the paint peeling later I'll do it.
