I went with powder coating. The reason, anodizing scratches really easily. Powdercoating is really tough. I don't want a scratched looking panel a few years down the line when a bunch of stuff hits the panel unexpectedly....and things will definitely hit the panel.
For me, Powder coating all the way.

Mike,
Powder coating is a plastic coating over aluminium, that tends to have a insulatory effect as well wouldn't you say

Assuming the tolerences are very tight if they don't compensate for the material build up, the instuments/screws may not fit if the powder coat is done after cutting.

Absolutely sure, they offer both options, at least per their technical sales guy..... |

Yes, you must allow for this in your design. They warn you about this as well. They also provide a spec on how much to allow. |

Brian, one of the problems with anodising is that you need an approved grade of aluminium alloy to get a decent surface finish. For instance Alclad aluminium will produce a terrible streaky result that you will NOT like.
If you are contemplating anodising I would recommend that you determine the alloy of your panel and then ask your potential anodiser if that alloy will produce an "architectural finish". Not many aluminium alloys are suitable for anodising if you require a high quality cosmetic finish (which I presume you do).
Powdercoating could be preferable. If so it might be worthwhile considering having the panel powdercoated only on the front side and edges so that any fittings that require grounding through the panel (if any) are able to make contact at the rear.

Thanks for the warning. While I am 99% sure I am going with powder coat, Front Panel Express's anodized panels look great and are very consistent. The samples they sent me are awesome looking. They use AA 5005 aluminum alloy. |

Yep, 5005 is a recommended anodising grade.

I suspect that almost everybody knows ---or at least would expect---that power coat is an insulator, but I doubt that the majority of folks know that anodizing is also.
I have run into issues in the past were folks have tried to attach a ground to anodized alum, and wondered why it did not work.
