I was in my favorite gun shop yesterday and...

The problem with polishing Aluminum guns is the loss of the hardness. All Aluminum guns (as far as I know) have to be
hard anodized. This a surface process that gives the alloy stregth. Not totally correct I know but as close as I can come to the correct answer without doing some techincal research. The hardest finish is black.

Cheers,

Removing the surface layer of an alloy frame will expose the softer alloy underneath the anodized layer. I wouldn't mess with it.
 
Fuel For Thought-

Kentucky Rifle My Friend,

Just a word of caution here! If the LEO took the Smith
& Wesson 642 from a teenager, the weapon should
have remained in the possession of the designated
departmental property clerk (evidence technican) until
such time that the case was cleared by the judicial
system. Otherwise, the LEO was in possession of a
stolen firearm! And I would not touch it with a ten
foot pole.:eek: :( :) In all likely hood, the LEO took
this gun from the juvenile, and kept it for his own
use; which is a felony! If the firearm wan't used in
a crime, it should be returned to its rightful owner
once the case has cleared.
