Black Paint?
Flat paints, also known as matte paints, are a valuable design tool when used correctly. Because they are non-reflective, they tend to conceal surface blemishes better than paints with more sheen. In a visual sense, these finishes effectively "smooth" dented or rough surfaces And, since flat finishes actually deflect attention from surfaces, flat paints are a great choice for surfaces you want to downplay.
Satin, low-lustre and eggshell have a sheen that is between semigloss and flat paints. Satin and low-lustre paints have a slightly higher sheen than eggshell finishes. Paints in this category are warmer and provide a greater appearance of depth than flat paints. They also resist stains better than flat paints.
Higher-gloss paint finishes can also help brighten dark spaces.
IMHO semi gloss or gloss are easier to maintain. I choose semi gloss for my frame and inner fenders.
