Take the tour ×  A big black vehicle rumbles through the streets
of the slum. Its battered exterior is encrusted with dust.
"Encrusted" means that water or oil has been combined with dust
(or something) and then applied to an object and allowed to dry
as a crust. So I think "encrusted with dust" has to be wrong,
but "encrusted with mud" could work. Am I right?  share|improve
this question Off topic (proofreading request). Incidentally,
the text is fine. –  MετάEd May 5 at 19:35 The use of
"encrusted" is not the issue with that. –  mattacular May 5 at
20:53 Could just say 'dusty' if you want to keep the dust. Or
'grimy'. –  lessthanideal May 5 at 21:24 "Encrusted" does not
require mixing anything with anything. Neither water nor oil
(nor dust, for that matter) need to be included in the process
of applying a crust to an object. You can encrust salmon with
crushed macadamia nuts, and you can encrust a lamppost with
partially melted English toffee, if you so desire. –  John M.
