Repair Procedure For Severe Acid Rain Damage

SANDING AND REPAINTING:

If it has been determined that the acid damage has penetrated more than 1/2 mil on a metallic or pearl color, or 1 mil on a solid color after color sanding, the following guidelines for sanding and repainting should be followed:

1. Wash vehicle surface using mild automotive soap & water and rinse with Deionized Water until all residue is removed. Clean the affected areas with an appropriate silicone/wax remover (DuPont 3939, PPG DX330/DX380 or equivalent*).


2. Using a dual action (DA) sander, completely sand affected areas as required to eliminate any depressions in paint surface

Note: While it is recommended to sand down into the primer coat, the underlying ElectroDeposition (ED) coat should not be exposed as it provides essential corrosion protection.


3. Finish sand the surface with wet-dry sandpaper using grit # as recommended by paint manufacturers.

4. Wash vehicle surface using mild automotive soap and water. Rinse with Deionized Water until all residue is removed from the surface. Clean sanded areas with an appropriate silicone/wax remover (DuPont 3939, PPG DX330/DX380 or equivalent*).


5. Apply a quality urethane enamel color coat or base coat/clear coat as required for maximum repair durability (lacquer-type paint is not recommended for this application). Follow the paint manufacturer's recommendations for detailed application of paint as required.

* Check with State and Local ordinances regarding use and disposal of all chemicals.
