Paint, Ferrous Metal Contamination, Acid Rain Discoloration Or Etchin
This TSB article is being republished in its entirety to add vehicles and model years, and to revise the procedure to use Ford brand service parts.
ISSUE Ford Motor Company has released a private labeled material to be used for iron particle/acid rain service repairs.
ACTION To remove these particles/contaminates, use ONLY the following products and procedure. No polishing, compounding, color sanding, or repainting should be done before this procedure is performed. This procedure uses products that are acidic, alkaline, and neutral and must be properly mixed and used in their specific order. Refer to the following Service Procedure for details.
Service Procedure
NOTE: ANY CHANGES TO THIS PROCEDURE WILL CAUSE AN INCOMPLETE OR UNSATISFACTORY REPAIR. THE USE OF ANY OTHER PRODUCT OR PROCEDURE MAY CAUSE DAMAGE TO ALUMINUM OR PAINTED SURFACES.
Identification
To assist in identifying surface contamination, use a (Tandy-Radio Shack #63-851) 30x lighted magnifier.
Concern Description
Ferrous Metal
Light Colored Vehicles: Small orange stains the size of "mechanical pencil lead." The surface is rough to the touch.
Dark Colored Vehicles: Small white or silver appearing dots with a rainbow ring around the dot. The surface is rough to the touch.
Industrial Fallout
Water spots with ferrous metal are present and the surface is rough to the touch.
Acid Rain/Etching
Surface will exhibit irregular discolored spotting.
Dark colored vehicles may exhibit cloudy or graying spots where the acid has begun to etch the paint.
Extreme cases of etching will be visible and may be felt.
Decontamination Procedure
Use Ford Acid Neutralizer, Alkaline Neutralizer, and Detail Wash to decontaminate and neutralize the paint surface. Perform the procedure only on vehicle when the paint surface temperature is cool. Follow the step-by-step procedure listed below to perform this service operation.
Rinse off dust, dirt, and debris with cold water. Flush liberally.
Prepare Acid Neutralizer by mixing 8 parts of water to 1 part Acid Neutralizer in a bucket.
Use a clean wash mitt and apply mixture of Acid Neutralizer to the entire vehicle starting at the top of the vehicle working toward the side. Keep the vehicle wet with solution, lightly agitating for 5 to 7 minutes. For vehicles with severe conditions, work the product for up to 8 minutes.
NOTE: USE A SEPARATE MITT FOR EACH PRODUCT. DO NOT INTERMIX MITTS.
Rinse the vehicle thoroughly with cold water to remove Acid Neutralizer.
Dry only the horizontal surfaces of the vehicle at this time. Do not dry glass.
Alkaline Neutralizer is ready to use. Do not mix with water. Pour the contents into a dispenser squirt bottle. Squirt Alkaline Neutralizer directly onto a clean wash mitt. Do not spray Alkaline Neutralizer on the painted surface. Apply the product to the vehicle, keeping the areas wet and lightly agitated for 5 to 7 minutes. For vehicles with severe conditions, work the product for up to 8 minutes.
Rinse the vehicle thoroughly with cold water.
Prepare Detail Wash by mixing 29.5 mL (1 ounce) of Detail Wash to 3.7 L (1 gallon) of water.
Shampoo the vehicle with Detail Wash using a clean wash mitt. Rinse the vehicle with cold water and dry the vehicle completely.
NOTE: DETAIL WASH IS A HEAVY DUTY NEUTRAL SHAMPOO CONCENTRATE (pH 7) AND MAY BE USED FOR HAND CAR WASHING OR IN AUTOMATIC CAR WASH SYSTEMS.
Surface Correction Following Decontamination/Neutralization
Visually inspect paint surface for evidence of removal of ferrous metal particles and water spots.
NOTE: ACID RAIN DISCOLORING OR ETCHING WILL REQUIRE ADDITIONAL PROCEDURES DEPENDENT ON DEPTH OF DAMAGE; POLISHING, BUFFING, COLOR SANDING, OR IN EXTREME CASES, REFINISHING.
Do Not Intermix Buffing Products. Use only one manufacturer's products.
Always follow the manufacturer's product usage sequence. Use the appropriate recommended pad at recommended buffing speeds as specified by the product manufacturer.
NOTE: WHEN ATTEMPTING TO AFFECT A REPAIR BY BUFFING, POLISHING, OR COLOR SANDING, DO NOT REMOVE AN EXCESS OF 0.3 MIL OF PAINT FILM OR REFINISHING WILL BE REQUIRED. USE OF AN ELECTRONIC MIL GAUGE (ROTUNDA 164-R4025) IS HIGHLY RECOMMENDED TO INSURE CONTROL OF PAINT FILM REMOVAL.
Use a dual action sander with a Velcro backing plate and a foam pad to fine polish and remove any swirls created by a rotary buffer or pad.
Use an alcohol and water mixture (1 to 1 ratio) to clean the buffed areas and to verify removal of scratches and swirls before application of the final polish.
