Thanks for the reply Richard!
Great find on the 5/8 adapter I totally missed that. I have seen the dremel buffing pads but they are so small it would take ages I would think to finish off my four rims.
Anyone have any input on the whole what is too fast piece? Ideally I would love to use the rotozip just because it would be easier to move it around rather then move the rim around the polishing wheel (wheel is pretty heavy)
