Paint: Service and Repair
Environmental Fallout (Acid Rain)
Since the severity of the condition varies from area to area, proper diagnosis of the damage extent is critical to the success of repairs. Perform diagnosis
under high intensity fluorescent lighting, on horizontal surfaces (hood, roof panel, rear compartment lid) after the surfaces have been properly cleaned.
There are 3 basic types of acid rain damage:
Surface Level Contamination
May be repaired by simply washing the vehicle, cleaning the surface with a silicone, wax and grease remover, neutralizing acidic residue and finesse
polishing. Refer to Surface Level Contamination Repair in this procedure.
Clearcoat Etching
Slight etching still noticeable after the above washing and finesse polishing procedure. Refer to Slight Clearcoat Damage - Wet Sanding, Finesse
Polishing in this procedure.
Basecoat Etching
Severe etching beyond the clearcoat into the basecoat. Refer to Basecoat/Clearcoat Paint Systems.
Slight Clearcoat Damage - Wet Sanding, Finesse Polishing
NOTE: Removing more than 0.5 mils of the clearcoat can result in early paint failure. The clearcoat contains ultraviolet screeners. Do not finesse sand
more than what is required to remove the defect.
IMPORTANT: Always refer to manufacture's packaged instructions for the detailed procedures of materials used for compounding or polishing.
1. Select a small test area on the damaged panel.
2. Readings of the paint film build should be taken prior to the operation. Refer to Paint Gauges.
3. Wet sand the damaged area using an ultra-fine sandpaper and rubber sponge sanding block. Refer to the manufacturer's instructions for detailed
procedures for the materials used in the repairs. During the wet sand process:
1. Use ample amounts of water.
2. Work slowly in order to prevent removing too much clearcoat.
4. Remove the excess water with a rubber squeegee and inspect the area. If wet sanding has repaired the damage, continue the sanding procedure on
the entire panel.
5. Apply a finesse-type polish with a foam pad. Remove any swirl marks with a dual action orbital polisher and foam pad. Refer to Clearcoat Repair
Specifications - 3M Products or Clearcoat Repair Specifications - Meguiar Products. If (during the repair) you suspect or observe that etching has
penetrated into the basecoat, too much clearcoat has been removed during sanding or base color is transferred to pad during polishing, the affected
areas may require clearcoat/basecoat application or refinishing. Refer to Basecoat/Clearcoat Paint Systems.
6. Polish the entire vehicle after all damage has been repaired.
Surface Level Contamination Repair
NOTE: Removing more than 0.5 mils of the clearcoat can result in early paint failure. The clearcoat contains ultraviolet screeners. Do not finesse sand
more than what is required to remove the defect.
IMPORTANT: Always refer to manufacture's packaged instructions for the detailed procedures of materials used for compounding or polishing.
1. Thoroughly wash the repaired area.
2. Dry the area thoroughly.
3. Clean the affected area with silicone, wax and grease remover.
4. Neutralize left over acidic residue by cleaning damaged areas with mixture of baking soda and water (1 tablespoon of baking soda per 1 quart of
water). Rinse thoroughly and dry the panel completely.
5. Apply finesse-type polish with a foam panel. If damage has been repaired, remove any swirl marks with dual action orbital polisher and foam pad.
Refer to Clearcoat Repair Specifications - 3M Products or Clearcoat Repair Specifications - Meguiar Products.
6. If some damage remains, refer to Slight Clearcoat Damage-Wet Sanding, Finesse Polishing in this procedure.
