Just wanted to share my experience with this. Yesterday, I finished the sanding, buffing and polishing procedure on one of my scoops. I'm confirming that the consistency, not so much the quality of the metal will yield less than perfect results. After the regiment of sanding through the various grit of sandpaper, I continued to machine buff then machine polish. I've found that where the consistency of the original casting is good, a perfect mirror polish results. Where the casting is less consistent, the black runs that Jean mentioned appear. The more you buff, the more they appear. They aren't really black but you can see that the metal is different in those places. Light refracts differently from there. Mind you, you need to be 12" away from the scoop to see the blotches but, never-the-less, they are there. In my opinion, polished aluminum does have a much richer look than chrome. Another benefit of polishing is, if you don't like the results, you have just prepared the part for chroming. Chrome will only look as good as the surface it's applied to. I personally can't justify the cost of chroming. I'm more than content with my results. Sure, it was labor intensive, but I took great pleasure of doing the work myself and pride in the results. Now, I'll start the whole process again for the other scoop. I haven't given up yet on getting those blotches out. I will try going back to the 1500 grit to see if I can take them out. They could be the result of the heat generated by buffing and might be eliminated by a softer touch on the buffing wheel. I'll post the results.
