How Long Can Spray Paint Last?
2 Answers
Spray paint can last for about half a year. Here are some precautions regarding spray paint: Maintain Spraying Distance: Before using spray paint, shake the can repeatedly to fully mix the acrylic inside. During the spraying process, maintain a distance of about 20 centimeters. Spraying too close can cause bubbles and buildup, while spraying too far can waste the paint. Dust Prevention: During spraying, be mindful of dust and other contaminants, as even a small insect can damage the freshly painted surface. Pay attention to the ambient temperature and humidity to avoid direct sunlight, excessively low temperatures, or overly dry conditions. When using spray paint, allow a few minutes between each coat, repeating the process several times.
Last time my car door got scratched, I fixed it myself with spray paint. The result was okay but not as good as professional painting. Parked outdoors, it started fading in less than half a year, especially after summer sun exposure, the paint turned white. If parked in a garage with the surface properly sanded before spraying, applying thin multiple coats plus a protective clear coat, it could last over a year. The most annoying part is that high-pressure car wash jets easily peel off the paint at the edges. So it's passable for temporary touch-ups on small scratches, but definitely won't last long for large areas.
