Paint - Lack of Adhesion to Anti-Chip Surfaces

Number 83-T-23 Section 2 Date 04/83
Subject: LACK OF PAINT ADHESION TO ANTI-CHIP SURFACES - 1983 OSHAWA BUILT 6000 MODELS
An apparent stone chipping condition on the rocker panels, dog legs and behind the wheel openings, is actually due to a lack of paint adhesion in the areas of the anti-chip material. This has been reported on 1983 Oshawa produced Pontiac 6000's SOP through D1211201.

This is a manufacturing problem caused by an inadequate application of the sealer coat between the primer and topcoats. The condition can be confirmed by applying a 3" strip of masking tape to the affected areas. Remove the tape using a quick snapping motion and note the removal of the topcoats with the tape.

To repair this condition, it is only necessary to remove the lacquer topcoats. A lacquer removing solvent will do this without disturbing the factory prime and anti-chip material. A sealer coat will have to be applied as specified below.

The following procedure will result in a successful repair of this condition:

1. Remove the lacquer top color and ground (same color as the prime) coats using a lacquer removing solvent or an acrylic lacquer paint remover such as, RM Feather Edger #830, Dupont Acrylic Removing Solvent #3907-S or equivalent. These solvents will not disturb the factory prime. No sanding should be necessary.

2. Thoroughly clean the area using RM Pre-Kleano #900, Dupont Prep-Sol #3919-S or equivalent.

3. Apply a sealer coat per the manufacturer's instructions. Use RM Clear Adhesive #811, Dupont Clear Adhesive #2129-S or equivalent.

4. Apply the acrylic lacquer color coat.

5. Allow to dry and compound as required.
