Omni and Shopline are low end paints used for quick insurance / car lot repairs. I use it to paint equipment and such but it does take more liquid to cover. ( Be sure to use hardener )

For car use I'd only use it in solid colors and for better than nothing repairs.

There is only one black the world over. ( Slate metallic does not count as it is more dark gray not black. ) White on the other hand has a few shades.
