Oxidation is the dulling and/or hazy appearance of a vehicle's top paint or clear coat finish. Oxidation is caused by accumulated exposure to ultraviolet light and environmental pollution. Black, red and dark color paints oxidize quicker because these pigments absorb more ultraviolet light than light color paints.
The effects of weathering or outdoor exposure on painted surfaces. Oxidation results in a dull or hazy finish. It can be corrected by removing the oxidized layer of the finish. Depending on the severity of the oxidation, this may be accomplished using cleaner wax, rubbing compound, polish or a machine glaze. If the paint finish is a metallic finish then power polishing is not very effective as the small metallic particles can be exposed to the atmosphere resulting in light steaks to the polished paint
