Vehicle spray painters use spray guns to spray paint onto the bodywork of vehicles and other items, to change the colour or to repaint scratched or damaged paintwork.
When repainting damaged paintwork of a vehicle, they prepare the body work by removing dirt or grease; they smooth parts that are rough or have been panel beaten; remove old paint with sandpaper or paint-removing chemicals; they cover the rest of the bodywork with paper in order to protect it; then they apply a preliminary coating of primer and a thin layer of primer-filler.
Spray painters mix paints until exactly the same shade as the rest of the vehicle is obtained before the final four or five coatings of the required colour are applied. Paint has to be applied evenly and each coat is allowed to dry thoroughly.
