If you have not used an air-brush before, this is a skill that also needs mastering. I use a/b for ceramic restoration and it took a few weeks and lots of failures to get the knack......then lots of practice. A/bs vary from those used for spray tanning to highly professional with interchangeable spray jets etc. A variety of pumps are also available depending on paint viscosity and pressure required.
Worst issue is overspray (the dry speckled area around the repair), and this can take hours to sort out

So even with my experience, have I touched up Aero?.............No, I shall leave it to the experts.
