For this mission, be sure only to use medium velocity and short-force settings. High pressure hurts the paint job of the vehicle, so be calm on polishing. Rotate it in circles as it turns, with the buffer going.

It is possible to burn the paint by applying too much pressure, so start light and add more weight if the compound needs to rub.
