i only used 400 grit sandpaper to sand it down until all the chrome was off and it became white, if you start to get to deep it starts to turn black. stop sanding that area of that occurs. it takes a little effort because of the angles you have to get into towards the sides. i sanded it by hand and couldnt see how it could have been done nicely with a power tool. i sprayed one coat of dupli color primer, layed down 4 layers of glass black and 8 layers of clear, let it dry for 2 hours and reinstalled.
