Chevrolet Trax: Clearcoat repair without repainting
Repair Procedure
- Thoroughly wash the repair area with Liquid Wash and Wax GM P/N 1052870
or the equivalent.
- Environmental damage may be corrected. Refer to Environmental Fallout (Acid
Rain), or Rail Dust
Damage Repair.
IMPORTANT: Follow all of the instructions from the manufacturer
of the polishing
material.
- Use a paint gauge before, during, and after sanding and/or polishing, to
avoid removing too much
clearcoat. Refer to Paint Gauges.
ENVIRONMENTAL FALLOUT (ACID RAIN)
CAUTION: Refer to Clearcoat/Ultraviolet Screeners Caution .
NOTE: Always refer to the manufacturer's packaged instructions for
the detailed
procedures of materials used for compounding and/or polishing.
Since the severity of the condition varies from area to area, proper
diagnosis of the contamination extent is
critical to the success of the repairs. Perform the diagnosis under high
intensity fluorescent lighting on the
horizontal surfaces (hood, roof panel, rear compartment lid), after the surfaces
have been properly cleaned by
washing the vehicle with a GM approved Liquid Wash and Wax kit.
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.
Clearcoat Etching
Slight etching is still noticeable after the above washing and finesse
polishing procedure. Refer to Slight
Clearcoat Damage - Wet Sanding, Finesse Polishing.
Basecoat Etching
Severe etching beyond the clearcoat into the basecoat in the affected areas
will require refinishing. Refer
to Basecoat/Clearcoat Paint Systems.
Surface Level Contamination Repair
- Thoroughly wash and dry the contaminated area with a GM approved Liquid
Wash and Wax kit.
- Clean the affected area with silicone, wax and grease remover.
- Remove and neutralize acidic residue by cleaning the contaminated areas
with a mixture of baking soda
and water (1 tablespoon of baking soda per 1 liter or 1 quart of water).
Rinse thoroughly and dry the panel
completely.
- Apply finesse-type polish with a foam panel. If damage has been repaired,
remove any swirl marks with a
dual action orbital polisher and foam pad.
- If some damage remains, refer to Slight Clearcoat Damage - Wet Sanding,
Finesse Polishing.
Slight Clearcoat Damage - Wet Sanding, Finesse Polishing
- Select a small contaminated test area.
- Film thickness should be taken prior to the sanding and polishing. Refer
to Paint Gauges.
- Wet sand and finesse polish the contaminated test area. If during the
polishing 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
the polishing pad during polishing, then the affected areas will require
refinishing.
Refer to Basecoat/Clearcoat Paint Systems.

Paint thickness gauges measure the total thickness of the vehicle finish. It
is important to accurately measure the
thickness of the finish on each vehicle as the thickness of the finish will vary
