Polish and matt finish on anodised Al

I have a Al part that have 2 finishes, sandblast and polish, on one piece for decorative purposes. The anodiser explains that we can't have them both, we can either choose to have polish and not-so-matt surface or vice versa. Is there any way to get round this?

As long as a GOOD, EVEN, job has been done on the blasted surfaces (youll have better results with glass bead blasting, then sandblasting), there is absolutely no reason why the part couldnt be anodized to your satisfaction.

The various finishes will have no recourse on the anodizing finish. Many many parts are done that have different surfaces. Some machined, some turned, some knurled and some polished. This should make no difference whatsoever to your anodizer. It can be done.
