I totally finished one, started the other and discovered many areas that needed work only to go back and forth remove more and more. I will post the final pics... The hardest area for me is the bowl area. Trying to get a nice clean finish takes so long. Any idea's? I was using a polishing (green) round stone that took forever... Maybe 4-5 stones and 2 hours on each plate. Also the center plate is going to be fun port matching it to a RE mani. Mucho to remove.....

I dont take the bowl down past a normal orange sanding stone, you can really change the final texture by the pressure you apply, I dont believe it really smoothing stuff out to the polished level, mazda doesnt do it with the renesis and if I remember correctly even have what they call the "Anti Wet" port on the renesis to help with fuel atomization.
