Coating Preparation and Applications
1990 Ford Ranger 4WD L4-140 2.3L SOHCSECTION Coating Preparation and Applications
The abrasion resistant coating is available in quart cans. About two quarts will be required for an initial installation on a passenger car similar to a factory-applied system. Slightly more will be required for a larger vehicle such as an Econoline.
The specified dry film thickness of 15 to 20 mils (.015 to .020") will require at least three or possibly four applications of coating material, with flash off time allowed between coats. As with painting, spray coat the complete lower panel.
The adherence of this coating to properly prepared sheet metal is excellent and it is not necessary to prime the repaired sheet metal. However, adhesion will be adversely affected unless the sheet metal (either repaired or new) is prepared in accordance with the following procedure.
