The trouble with the current entry, though, odondon, is that it says:
dusted quality - angestaubte Ware
which just doesn't fit, unless you said something like "dusted-quality goods" (not that I would say that!)
Leo has some entries for "dust" in the meaning you mention:
dust 2 to sprinkle something with a substance in powder form. http://www.chambersharrap.co.uk/chambers/feat...
to dust abstauben
to dust streuen
to dust überpudern
to dust off abstauben
to dust off abwischen
to dust off wegwischen
to dust over überpudern
... from which you could work out what a dusted finish, dusted quality, dusted look, etc. are. I don't think any of these need their own entry, but I agree that another entry for "dusted" as an adjective would be useful. I don't think "anstauben"/"angestaubt" fit in this context either, though, as they mean to collect dust, not to deliberately add it to something:
an|stau|ben : ein wenig staubig werden: Wäsche, leicht angestaubt, billig abzugeben; angestaubte Bücher.
