Whistule, you could always take some nails and hammer them through a board to make your own rake. It'll be much stronger, and will probally clean the part a little better than a saw blade. When i do my polishing, especially on more dense peices, i always keep a hand held propane torch handy, that way i can heat up parts slightly so they take compound better and clean up easiar. I have also found that, a certain amount of cloudiness is expected with polishing aluminum. From examining other parts, even polished SS, it seems that from certain angles, there is still a slight haze. My personal test is bringing it outside in the sun, if you can see a haze, than it needs more time on the buffer. Good luck!
