Body damage is extensive and deformation has already occurred. The actual working time should be completed within 2 to 7 days. Here is additional information: Determine the repair scope: Carefully inspect the damaged area. If the damage exceeds one-third of the component, an over-repair method should be adopted. Assess the extent of damage: For shallow scratches, no putty is needed; sand directly until no marks remain before proceeding to the next step. For deep scratches or small dents, putty is required. If there is deformation, metalworking treatment is necessary. Construction protection: Prepare the relevant materials and tools, and use tape to protect components other than the damaged part, especially edges and corners, to prevent unnecessary damage during sanding.

The time required for touch-up painting is indeed variable, primarily depending on the extent of damage and the repair method. For minor scratches like slight abrasions on car doors, using a touch-up pen for a quick fix might take only 30 minutes to an hour, as the technician cleans the surface and applies the paint, which dries rapidly. For more significant damage, such as a dented bumper that requires full repainting—involving multiple steps like sanding, priming, color coating, and clear coating—each layer must dry properly to avoid bubbles or imperfections, typically taking a full day or two. Hot weather can speed up the process with a baking booth, but high humidity in winter prolongs drying and may compromise quality. From my experience, quick fixes are faster and cheaper but prone to rework, while professional shops, though time-consuming, offer more reliable results. It's advisable to consult in advance for an estimate to avoid delays. Generally, repairs can range from half an hour to 48 hours, depending on specifics—don’t rush and risk poor results.

Last month, I had a small dent on the rear of my car that needed touch-up paint. I dropped it off at the designated repair shop at 8 a.m. After inspection, the staff said the paint damage wasn’t deep and could be fixed the same day, taking about three to four hours, including color matching and drying. I went shopping and was notified in the afternoon to pick up the car—quite satisfied with the speed. However, my colleague had a major scrape two years ago that took a whole weekend to repair because multiple paint layers dried slowly. When the repair shop is busy, queuing might add half a day. The key factors are the size and complexity of the damaged area. Simple paint jobs can be done in hours, while major repairs involving sanding and filler materials naturally take longer. After repair, avoid washing the car or exposing it to direct sunlight immediately to allow the paint to strengthen. My experience: minor touch-ups are quick, major repairs take longer, averaging between a few hours to two days—plan accordingly.

The duration of paint touch-up varies based on the extent of damage: minor scratches can be repaired, including cleaning, painting, and drying, within one to two hours, especially with quick-drying tools. Larger areas, such as a full door repaint, require more steps—sanding and rust treatment take about an hour, followed by primer application and drying for another hour. Multiple layers of base paint are then applied with drying intervals, and finally, clear coat and baking, which is crucial for color protection and gloss. This process typically takes eight to twenty-four hours or more. A paint booth can reduce the time, but color matching is time-consuming and often causes delays. For standard repairs, it's advisable to allocate a full day to allow the paint to fully harden, ensuring durability. Driving safety considerations may also affect the total duration.
