Paint Problem
Have a '87 300E with gray blotches under clear coat on the trunk lid (see photo) and would like to know what caused this and how to get rid of it.

~One man’s opinion / observations~
Oxidation:
Paint oxidation (reduction) is caused by environmental pollutants (acid rain, ozone, industrial pollutants, hydrocarbons, etc) the suns heat (which also causes paint colour fading from UV radiation) inclement weather or the use of harsh detergents. Commercial car washes using strong detergents will leach out the oils in the paint and dull the paint film surface even faster
It starts as a chemical reaction that causes the paint film surface to overheat, dry out and oxidize leaving microscopic surface imperfections and micro pores in the paint film surface that are vulnerable to deterioration. Once the air borne contaminates and pollution compromise the paint surface they accelerate the oxidation (reduction) process
It can appear as a dull and somewhat hazy, or `chalky' appearance to the paint surface, a paint film surface that is adequately protected with wax or a sealant actually has a lower surface temperature than one that is not. A dark coloured vehicle parked in the sun can attain a surface temperature in excess of 200° F
Clear coats are usually a polythene or urethane paint, that are formulated from oils, they are used to protect modern water-based paints as they provide a tough and durable protection
Primarily a hostile environment will remove the paint films sacrificial barrier and then remove the oils from the paint (paint) clear coat, leaving an unprotected surface with its microscopic gaps and valleys, allowing environmental pollutants to penetrate, which accelerates the degrading of the paint film surface eventually leading to clear coat failure and subsequent re-painting. (See section 19)
To remove paint surface oxidation; use detailers clay to remove any surface contaminants, a solvent type chemical cleaner/polish (Klasse All-In-One) and then a suitable abrasive polish (dependant upon how severe the problem) to remove the oxidized paint (Iz Einzett Ultra Paint Polish™ or Paint Polish™) with a cutting foam pad (LC orange or yellow, seed #4) and then apply a sealant and / or wax protectant.
~Hope this helps~
