There are three levels of oxidation and they all can be resolved in three different ways with different products. It is a concern you might want to address right away so to avoid your car paint from flaking off.
If you leave your car unprotected and out in the elements, the paint will most likely oxidize. The first level of oxidation will happen and you will not notice it over a period of a month or more. Light oxidation can be treated through regular paint cleaning and polishing. Waxing your car after each cleaning will also help protect your car’s paint.
The second level of oxidation is moderate oxidation. Just like light oxidation, it can be repaired using a cutting polish. The hardest oxidation to deal with is heavy oxidation. This may happen after a year of your car being unprotected. This can be described by a dull, chalky surface on your car’s paint. It may even be difficult to restore but there are products you can always try before getting a paint job done. An example of a product you can use for heavy oxidation is XMT Heavy Duty Swirl Remover #4 Polishing Compound. It will be hard to conduct a restoration using only polish.
if you are trying to remove the oxidation from your car paint:
Always apply the compounds in small area and work it in then remove it right away. Also use a wet, clean cloth to apply the compound to avoid swirl marks then wipe it off with a dry soft cloth. Remember to work with the least abrasive polish and work your way up if the least abrasive polish didn’t do the job. Until all the white chalky substances are removed, continue rubbing your vehicle. Occasionally change to a new, clean towel to avoid incurring swirl marks on your vehicle as you work the compound.
To prevent car paint oxidation from appearing, you might want to keep your vehicle clean at all times. It is important to remember that UV rays and the elements break down the paint on your vehicle and cause oxidation. To help slow down the process it is recommended to keep your vehicle in a garage or covered and protected from the sun. If you have any concerns about your cars surface, consider consulting a professional detailer.
