[ARC5] Satin finishing aluminum

[Mike Hanz]

Some alloys don't polish very well, Ken.  If it has been anodized, you 
can't polish it until you break through the hard anodize layer.  At any 
rate, I use a buffing wheel when I can, along with a white rouge made 
for aluminum.  Plain sheet aluminum responds beautifully to a product 
called met-all aluminum polish, which many in the aircraft community use 
- corn starch is an effective diluent to make it go further.  Generally 
less than $10 a can.

Best wishes,
Mike
