caring for a matte finish

though i am a way off on painting my car. i was wondering how do you care for a matte finish. I know some guys have flat black hoods. you couldnt wax them right? what do you do just wash it? what happens the first time you get a greasy hand print on the fender? i was considering a medium to light blue matte finish. very similar to the paint that is already on it. even though it wasnt meant to be matte.
