Apply paints, dyes, polishes, reconditioners, waxes, or masking materials to vehicles to preserve, protect, or restore color or condition. Monitor operation of cleaning machines and stop machines or notify supervisors when malfunctions occur. Clean the plastic work inside cars, using paintbrushes. Car polishing is the process of removing minor clear coat damage (scratches and swirl marks) using a polishing liquid to flatten the clear coat which increases the gloss-level. The polishing process can be performed by machine or by hand and should be followed by protecting the paint using a wax, sealant or coating.
