This procedure is being published to advise all body and paint technicians about proper procedures for preparation of service sheet metal parts coated with Electro Deposition Primer (E-Coat).
When preparing a panel for paint, it is important to leave the E-Coat intact. Do not sand off the E-Coat. Refer to the following Service Information for details.
Service parts built after October 1, 2001 are coated with a non-leaded epoxy based E-Coat, which is a change from the previous E-Coat product. The E-Coat composition change makes it necessary to eliminate unnecessary sanding to protect the part from corrosion. Improper preparation with excessive sanding of the E-Coat to bare metal is more critical than in the past and will jeopardize the sheet metal warranty and overall customer satisfaction.
Light scuff sanding using a Scotchbrite pad or wet sanding with 320 grit sand paper is all that is necessary to obtain a mechanical scratch (bite) for the primer/topcoat paint material. This is applicable for general panel preparation and minor paint flaws only.
If the sheet metal panel contains more than a minor flaw (i.e. dents, large paint blisters) in the E-Coat, it should be returned. Contact your Customer Service representative for details.
Refer to Figures 1 through 3 for the chemical facts sheets applicable for the new E-Coat product.
