The automotive refinish industry works to repair and restore the exterior paint and surfaces of vehicles. Refinishing is necessary when a vehicle's paint becomes damaged from accidents, wear and tear, or environmental factors like sunlight, rain, and hail. The industry employs techniques to return vehicles to their original appearance through paint repair and matching processes.
Automotive Refinish Sanding and Surface Preparation
Proper surface preparation is crucial for a high-quality paint job. Technicians will first assess any dents, scratches or other imperfections and make any bodywork repairs. They will then carefully sand the repair area to remove any loose or damaged paint using progressively finer grit sandpaper. This sanding process creates a smooth surface for the new paint to adhere to. All surrounding areas will also be sanded to help the new paint blend seamlessly. Any grease, wax or contaminants are removed with a cleansing solution to ensure optimal paint bonding.
Priming and Basecoat Application
After sanding, technicians apply a layer of primer to the prepared area. Primer acts as an adhesive layer and filler to create a smooth base for the color coat. Automotive refinish Most modern primers are electrostatically charged, allowing them to adhere evenly across nooks and crannies. With the primer dry, technicians carefully apply the color-matched basecoat using a spray gun. Like primer, the basecoat is typically applied electrostatically for an even coat. Multiple light coats are preferred over one thick coat to avoid runs or sags.
