Cant say, its a touchup... And black often is not black at all, often there is some color in it. Black is one of the hardest colors to touch-up if you do not know what is on it. Maybe you can ask to measure the color for you in a paint/repair shop? Thats what I always did, measure the color, get the recepi and mix-match to it. (I made the color for the painters)
Also you get some different blacks in Auto Air, make some testpanels with the clear over it maybe gives a clue.
Jet black, black, transparant black, black basecoat. They all look different.
Sorry, no clear answer on how to get it the same... Maybe someone else with experience of Auto air can give a direction?
