For highly oxidized paint try the following;[/i][/b]
Wash the paint surface and dry thoroughly
Clean the paint with chemical paint cleaner (Klasse All-In-One) using an orange foam pad at speed #4, this may take 2-3 applications
Once the oxidation has been removed use a decontamination system (Auto International A B C System
(http://www.autoint.com)
Apply an oil rich product to stabilize the paints binder system (3M Imperial Hand Glaze) apply a thick coat and allow to dwell for 12-24 hours before buffing, repeat as necessary until surface has an ‘oily’ sheen.
Remove residue and apply a Carnauba wax (Zymol Concourse)
Try to keep vehicle paint surface away from UV heat radiation
Keep paint surface waxed on a regular basis.
Unfortunately if the clear coat is failing a repaint is the only permenant fix.
