Painting a car takes patience and time to get the perfect result you desire. Most beginners make the mistake of painting the car once; however, professional painters know that multiple light coats of paints are better than using thick paint.

Another thing to watch out is that most painters are tempted to apply a large amount of paint in order to minimize the time investing in painting the car. Notwithstanding, the outcome won’t be what you expect if the paint runs and builds up.

Therefore, to avoid such situation, you should hold the spray nozzle 10 inches far from the car before applying even strokes. Furthermore, the strokes should be in a horizontal pattern. Don’t apply the paint in vertical strokes.
