i have a 1992 eg6 and im going to be painting it champ white but i need some help on what to tell the painter ex: i want to paint my door handles that stock black color but idk what its called, i also want to paint the side skirts stock black but idk the color for that neither, i have jdm thin side moldings im going to put on the car along with mudflaps

 

The parts your refering to maybe raw, textured plastic in stock oe form, unsure about the handles. I painted matched civic handles a long time ago and can't recall if they were raw or not. You'll have to choose between flat, satin and semi- gloss black to get the exact look you want. Have the painter show you examples, spray outs of each to decide. Every top quality auto paint systems offer these variations, some also in spray can form too.
