form another forum i am a member of: (i added the highlighs)
Ford/GM/Chrysler/MB/Porsche all have service directives dating back 20+ years up to today that specifically refer to paint correction/contamination procedures and clay bar is not a referred procedure and specifically identified as a method which only removes the surface level paint contaminants and as such, the "root' of the contaminant remains continues to destroy the paint from underneath the surface layer of the paint. I can certainly send copies of these docs to anyone who would like them but......
Just remember, Mequire's clay bar is rated at 3500 grit. There much better clay bar products out there rated at much finer grits (typically 5000+)- so if you are comfortable and believe your paint needs to be wet-sanded, and that is the only and safest way to correct the flaw/issue, then do so but remember, for 90% for all paint contamination issues there are products designed to relieve/remove/neutralize the contaminants without reducing the mil thickness of the clear coat
in the past 30+ years, I have only seen one car that I actually told the owner it needed to be "clay bar".....I have personally used the recommended products, available from any auto paint supplier to remove industrial/environmental contaminents of almost all types and been successful on lacquers, enamels, acrylic enamels, laytex & urathanes. These procedures date back to 1990 and are still published in current oem paint maintenance publications/service manuals.
