well thank you for that helpfull information .
 I was reading up on technical electronic vocabulary in a glossary supplied on line for something specific and came across anodize. It was described as use in heat sinking devices . I have seen the application on amplifiers and some power supplies.
 Then i tied that to some of the pieces my son had brought home to show off .
 He is a lathe machinist specializing in close tolerance optical devices . i really like the look of anodized.
 well i guess i might look a liittle deeper into it. ( i can get a decent deal for some quality work ! )
 I appreciate the advice James . Thanks
 Eric
 ps you are just jealous i am going Front mount arent you  ?
LOL : )
My reasoning in the background of all that had been to consider a black front mount.
and the goal was to NOT be seen actually .
 But i had not thought of stone chips. even though i could just touch them up with a thermal paint i suppose.
