flat black paint????

i've hd 2 restored black paint cars, black ( real paint!) requires absolute perfect body work or any blem will show, and its impossible to keep clean for sure!!! the flat black was anu idea i'd never considered, maybe best to just work on each panel as i can, then seal it till i can have the whole car painted at once, i'm allergic to bout any paint just about kills me. thanks for the comments
