1. Inventory of popular repainting topics in the past 10 days
| topic | heat index | Main discussion points |
|---|---|---|

2. Analysis of the whole process of touch-up paint in the repair shop
1.Damage assessment: The repair shop will first check the degree of damage to the paint surface and distinguish between shallow scratches (only the clearcoat layer is damaged) and deep damage (the paint layer or primer is exposed).
2.surface treatment: Key steps include:
| Cleaning and decontamination | Use special degreaser to remove oil film |
| polished smooth | P800-P1500 water sandpaper for step-by-step polishing |
| Masking protection | Protect surrounding undamaged areas |
3.Touch up paint construction: Modern repair shops mostly use the following processes:
| process | Technical points | Time consuming |
|---|---|---|
| Primer spraying | Epoxy primer to prevent rust, needs to be completely dry | 2-4 hours |
| Paint matching | Computer color adjuster + manual fine-tuning | 30-90 minutes |
| Varnish coverage | Spray 2-3 layers of 2K varnish | Including drying time 24 hours |
3. The five major issues consumers are most concerned about
1.price comparison: Repair shop repaint is usually 30-50% cheaper than 4S shop, but please note:
| Car door touch-up paint | 4S store quotation | Repair shop quote |
| Ordinary brand | 800-1200 yuan | 400-700 yuan |
| luxury brand | 1500-3000 yuan | 900-1800 yuan |
2.Color difference control: High-quality repair shops will use spectrophotometers (error ≤ 0.5ΔE), while ordinary shops may have a color adjustment error of more than 3ΔE with the naked eye.
3.Warranty service: Regular repair shops usually provide a 1-2 year warranty, and a written agreement is required to specify the treatment plan for problems such as fading and blistering.
4.time efficiency: It usually takes 2-3 days to repaint a small area (including the paint curing time). The quick repair service may be shortened to 8 hours but it affects the durability.
5.Environmental certification: It is recommended to choose a repair shop that is qualified to meet VOC emission standards. The water-based paint workshop must be equipped with a professional paint room.
4. New technology trends in touch-up paint in 2023
1.Nano ceramic varnish: The hardness can reach 4H (traditional paint 2H), and the UV resistance is increased by 3 times.
2.AI color grading system: Match complex metallic paint effects through deep learning, and the color difference is controlled within 0.3ΔE.
3.Partial touch-up technology: Using a micron-level spray gun, the repair range is accurate to 1cm², saving 30% of the cost.
5. Suggestions for car owners
1. For small area damage (≤3cm), you can try polishing first to avoid unnecessary spray painting.
2. Avoid high-pressure water gun cleaning within 7 days after touch-up, and do not wax within 30 days.
3. Choose a repair shop with CCC certification and check the brand authorization certificate of the paint used.
4. Keep 5% of the original paint for later color adjustment, especially for pearlescent paint/metallic paint models.
Through the above structured data and practical suggestions, we hope to help car owners handle the repaint problem more professionally and find the best balance between cost-effectiveness and quality.
