I've heard the better results have to do with a layer or two of clearcoat after the initial touch up color is layed in.
"Leveling" the chip has a lot to do with how light is reflected and hits the surface.
The last touch up job I had was Brembro brakes on the Infiniti, a very weird golden color. One day, I noted a Civic in town that had to be so close it was good enough. Went straight to the Honda dealer and order the 'pen'.
It worked well but those calipers are well hidden so perfect or close enough ? Who knows ....
