The first thing to do is to get the model to expose the areas that need to be airbrushed. This does not mean indecent exposure as certain areas can be left covered.
Clean the area and disinfect it to make sure that the surface is ready to apply the coat of paint using the airbrush.
Begin painting the model. However, ensure that the medical team is monitoring his or her vitals to ensure that she is under no stress or duress throughout the procedure. Make sure to give the model a basic breathing mask to keep all the harmful chemicals away from her lungs. You should also wear a mask while airbrushing to avoid inhaling any toxic fumes.
If the model begins fighting or you need to restrain her or him to limit their movements then have your assistant hold them in place while you airbrush the model. Try not to be forceful and constantly reassure the model that the airbrushing is almost done.
Allow the model to take a break with each layer or application of paint. You do not want to stress him or her out.
Once the painting is complete allow it to dry before the photo shoot or walk on the runway.
To remove the paint, use any product that is not too strong or full of chemicals as it could harm the skin of the model. Instead ask the model to take a hot shower and use a loofah to scrub the paint off. Remind the model to get all of the paint off to avoid any skin irritation later on.
