What Are the Aftereffects of Hood Repainting?
2 Answers
Engine hood repainting aftereffects include increased susceptibility to rust, as the repainting process damages the phosphating layer and electrophoretic coating. These two layers play a crucial role in preventing corrosion of the metal substrate. Once compromised, conventional repair techniques cannot restore them, making the vehicle prone to rust. Repainting considerations: 1. Touch-up paint colors are custom-mixed before repairs. While driving, paint gradually fades—imperceptible to the naked eye—but shows slight variations in fading intensity when viewed from different angles under sunlight. To achieve optimal color matching, on-site color mixing is essential. 2. If the original paint is pearlescent, imported paints should be used for touch-ups to ensure superior finish quality and enhanced weather resistance. 3. With meticulous operation, computer color matching can produce paint indistinguishable from the original color to the untrained eye.
Right after I had my car hood repainted, the paint started bubbling, and then the color gradually faded, looking really off. Turns out, if the surface isn't properly cleaned before painting, dust and other contaminants trapped underneath can cause the paint layer to peel over time and even lead to rust. I think the main issue was the paint shop not being professional enough, using low-quality paint or insufficient baking time. Now my hood looks worse, and sometimes the corrosion spreads, so I have to wax it regularly to prevent further damage. I really regret going for a cheap option instead of a reputable shop—this aftermath not only affects the appearance but could also reduce the car's value in the long run.
