3.4 PPG's Clearcoat Defect Removal

OEM manufacturer appearance and performance specifications can only be duplicated when properly applied.

Here is the Procedure and Recommendations directly from PPG

PPG - Clearcoat Defect Removal - PD-0804

______________________________________________________________
Caution: Wear the proper safety protection when sanding, cleaning, mixing and spraying all materials included within this process.
______________________________________________________________

PPG Automotive refinish clearcoat finishes are designed to duplicate OEM manufacturer appearance and performance specifications when properly applied using recommended procedures, undercoats and equipment.

Even with extreme care in cleanliness and preparation procedures, dirt and particulates can land in the clearcoat film during the application and drying process.

The OEM environment can not be entirely duplicated in a collision repair facility for these and other reasons:
• The vehicle is painted at the factory as a shell before any non-painted parts are attached,
• The vehicle can be cleaned thoroughly to eliminate dust and dirt, and has never been "on the road".
• The vehicle is painted with computer controlled robotics for consistent texture

When removing dirt and particulates from the refinish clearcoat depending on severity the procedure will require:
• Sanding or nibbing the affected area to remove the dirt and particulates
• When removing multiple spots in any given panel it may be necessary to gradually sand or level the texture away from the area from some or no texture in appearance to texture matching the OEM appearance. This procedure may entail sanding to some degree the entire panel.
• All areas sanded must be buffed and polished to bring back the desired appearance and DOI (Distinctness Of Image)
