Do you remove oxidation?

It really depends on the severity of the oxidation. Some cases are impossible and may actually require a new paint job. For minor cases, at the very minimum, a clay-bar treatment, wax, and buffing are required to even out those affected areas.  We recommend getting the Outright package and adding a buffing treatment. If you are completely unsure don't hesitate to send a picture via email to support@washos.com and one of our detail specialists will be able to give a better assessment.
