Section 01-00: Body—Service | 1993 Mustang Workshop Manual |
Use Elastomeric Additive for finishing flexible automotive exterior parts.
The product is intended for use with Acrylic Air Dry paints, or suitable equivalents to refinish flexible parts and is not suitable for use on metal.
This material adds flexibility to air dry paints so that the same paint with additive can also be used for repair of the soft, non-metallic parts. The use of standard repair automotive finishes on flexible parts is impractical as these finishes form a rigid coating when the paint cures. This additive allows the paint coating to adhere to the part when flexed and return to normal appearance as the part returns or recovers to its original shape.
WARNING: THE ADDITIVE MUST BE HANDLED WITH CAUTION. IT IS INTENDED FOR
INDUSTRIAL USE ONLY BY QUALIFIED PERSONNEL AND IS NOT INTENDED FOR THE GENERAL
PUBLIC. THE PRODUCT LABEL PROVIDES INFORMATION ON RECOMMENDED SAFETY
PRECAUTIONS AND PROPER APPLICATION. THE ELASTOMERIC ADDITIVE SHOULD NOT BE USED
UNTIL THIS INFORMATION IS READ AND UNDERSTOOD. OBSERVE ALL APPLICABLE
PRECAUTIONS.
THE VAPOR AND MIST SPRAY CAN BE HARMFUL. WHEN MIXED, IT SHOULD BE, IF POSSIBLE, USED IN A SPRAY BOOTH WITH ADEQUATE RESPIRATORY PROTECTION. THE RECOMMENDED PROTECTION IS A NIOSH APPROVED POSITIVE PRESSURE AIR SUPPLIED RESPIRATOR. IF THIS IS NOT AVAILABLE, USE A VAPOR/PARTICULATE RESPIRATOR SUCH AS 3M® MODEL NO. 6984 OR ITS EQUIVALENT, RECOMMENDED BY THE MANUFACTURER AS EFFECTIVE FOR ISOCYANATE VAPORS AND MIST. RESPIRATOR PROTECTION IS RECOMMENDED FOR USE DURING THE WHOLE TIME OF SPRAYING AND UNTIL ALL VAPOR AND MISTS ARE GONE. THE 3M® RESPIRATOR PACKAGE HAS SPECIFIC FITTING AND USAGE INSTRUCTIONS THAT MUST BE FOLLOWED TO ENSURE MAXIMUM PROTECTION FROM THE RESPIRATOR.
The Elastomeric Additive has a recommended shelf life of one year. A sticker is on the overcap stating a date after which the product should not be used.
The additive should be kept away from water or moist air because it may react with water and form a gel-like material which can make the product useless. The flexibility of the coating may be adversely affected if the relative humidity of the air is high during application. The container must be kept closed when not in use.
The usable "pot" life of a mixed color is approximately one hour, after which the mixture will have poor drying characteristics. To avoid waste of material, mix only the quantity required. Clean all spray equipment with solvent immediately after use. Allow part to cure two to four hours after final coat before handling. After curing for 24 hours, the coating can be rubbed out by hand to improve the finish. Do not use a machine for rubbing as this can cause burning.
Surface Preparation
If the flexible part has a coating that completely covers the substrate, no special priming is required. It only requires cleaning with a Silicone and Wax Remover and scuff sanding with 400-grit paper to remove gloss. The high bake elastomeric coating applied in the factory requires sanding to promote adhesion of the air dry service paints.
If the coating does not cover the substrate, Elastomeric Primer and Elastomeric Thinner must be used prior to applying the color coat. Follow label instructions for each product.
Mixing and Application
The additive is highly recommended for use with Acrylic enamel. It may also be used with Acrylic Lacquer for colors that are not available in enamel.
Apply full wet coats with 10 to 15 minutes flash time between coats.
Enamel: Requires three full wet coats.
Lacquer: Requires six full wet coats.
