F 250 2WD Pickup V8-6.9L DSL (1985)
^
Each technician performing the sanding operation MUST wear an approved respirator with high efficiency particulate filters (HEPA).
^
Technicians should use a dual action sander with vacuum collection equipment.
^
The vacuum equipment MUST be equipped with a HEPA filter on the air exhaust. Dealers are cautioned not to exhaust vacuum air into the
atmosphere and operators are cautioned to follow the manufacturer's guidelines for maintenance or replacement of the filters.
Remove all paint by sanding the affected areas to clean bare metal. Use 80/180 grit 3M Green Corp. Regalite Dust Free sanding discs or equivalent on a
D.A. vacuum sander.
RECOMMENDED PLASTIC MEDIA BLASTING PROCEDURE
Ford's testing has shown that plastic media blasting meets OSHA lead standard requirements and is efficient when the manufacturer's published
procedures are followed.
The operator must wear an air supplied hood using compressed air free from carbon monoxide, oil, water, and other contamination when performing this
operation. This process is safe to the operator and resists damage to vehicle sheet metal.
Plastic is the most popular blasting media for paint removal. Plastic media blasting requires removal of the remaining paint from the masked areas, and a
light and fast sanding of the entire vehicle using a dual action sander with 220 grit sandpaper. This surface preparation will provide excellent paint
adhesion. Other blast media such as Aluminum Oxide or Sodium Bicarbonate are not recommended.
CHEMICAL STRIPPING NOT RECOMMENDED
Ford Motor Company does not condone the use of chemical stripping. A majority of the chemical stripping products contain the chemical Methylene
Chloride. This chemical is on the Environmental Protection Agency's list of regulated chemicals and is on OSHA's list of chemicals with permissible
exposure limits. Injury to employees or the environment could result if proper precautions are not taken during its use.
MIL THICKNESS READINGS OF "BARE STEEL"
After removing all of the paint from the vehicle, zinc phosphate and galvanized steel coatings are left intact. The following information details the steel
coatings systems and body panels which have these systems:
^
(1985-1986) All body panels have Zinc Phosphate metal coating to a thickness of 0.0-0.1 of a mil.
^
(1987-1991) All body panels EXCEPT cowl, fenders, and bed side panels have Zinc Phosphate metal coating to a thickness of 0.0 - 0.1 of a mil.
^
(1987-1991) The cowl, fenders, and bed side panels are Galvanized to a thickness of 0.3-0.5 of a mil.
These specifications will effect the overall paint thickness readings.
3.
If minor rust is present, remove by sanding or use a small blast and vacuum system.
4.
Blow off the entire vehicle to remove loose dust and debris.
5.
After stripping, mask all areas on the vehicle that are not to be painted or will be affected by paint overspray (engine compartment, wheels, etc.).
Mask all mouldings not removed with Scotch Auto Body Protective Tape # 06945.
SURFACE PREPARATION
6.
Wipe all affected areas with a fast drying solvent. Wipe dry using a clean, lint-free cloth to remove all residue.
CAUTION:
KEEP WIPING UNTIL SURFACE IS COMPLETELY DRY. ANY RESIDUE MAY RESULT IN CONTAMINATION OF THE COATINGS TO BE
APPLIED FOLLOWING THIS STEP.
