Environmental Fallout (Acid Rain): Notes
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 Liquid Wash and Wax GM P/N 1052870. 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 .
