One more thing before you push up the cover; you'll have to remove the release button at the top center. Push a flat, stiff tool (or scrap of steel) ine from either side to depress the spring steel clips holding the bezel/housing in place. Lift it out of the hole and you will see two more screws to remove.
BTW, try painting a small trial area on the inside of one of those covers first, then when it dries, see if you can scratch it. If they are original covers you'll probably need a special plastic primer before paint.
