Hello Cathy,

Pretty open question....

Chemfilm ASTM B 449  Class 1 (least conductive), 2 and 3 (most conductive)
Personally if you want to be conductive I like class 2 (for ESD, grounding,
etc) the class 3 offers no environmental protection at all. (I learned that
the hard way.)

Anodize  ASTM B 580  Very nice finish, looks wicked high tech.  State color,
not requested very often but you can design a cheap cover, deburr and anodize
red with a black front bezel.  Nothing looks better.

Passivate  ASTM A 380  Can used on sheet metal but I always use or order
washers and that type of hardware with it.

Then there's painting... I find a nice pin stripe works wonders...

For more info search local phone listings under finish and sheet metal and or
sheet steel or enclosures.

Good luck,
Boston Brad
