II. Product Details (PRODUCT DETAILS)

1. Ultra-Fine Caliber Nano-Ceramic Nozzle, Touch-Up Precision Surpassing Traditional Tools

(1) Three Ultra-Fine Calibers, Covering All Precision Touch-Up Scenarios

• 0.5mm Ultra-Fine Nozzle: Designed for micro-scratches (e.g., hairline scratches on car clear coat, paint chipping on mobile phone screen frames), with atomized particle diameter ≤15μm and spraying width ≤3cm. It can precisely cover 0.1mm-wide scratches, achieving seamless connection between the touch-up area and the original paint, with repair traces invisible to the naked eye;
• 0.8mm Regular Touch-Up Nozzle: Suitable for electronic device shell touch-up (e.g., paint chipping on laptop A-side, earphone shell scratches), with spraying width 5-8cm and coating thickness controllable at 8-10μm. One thin coat can cover defects without repeated sanding;
• 1.0mm Small-Area Primer Nozzle: For touch-up of metal accessories (e.g., watch cases, car metal trim strips), first spray low-viscosity primer for rust prevention, then topcoat to avoid nozzle blockage. The adhesion after touch-up meets Grade 1 of GB/T 9286-1998 (no peeling).

(2) Nano-Ceramic Material, Dual Guarantee of Durability and Precision

2. 29PSI Ultra-Low Pressure Atomization, Precise Control Without Blurring

(1) Ultra-Low Pressure Design, Solving the "Edge Blur" Pain Point in Touch-Up

• Controllable Paint Mist: The atomization range is concentrated, with a diffusion radius of only 0.2m (0.5m for traditional touch-up guns). No large-area masking is needed during touch-up—only 1-2cm around the touch-up area needs to be covered, saving masking time;
• Seamless Thin Coating: Ultra-low pressure combined with ultra-fine nozzles enables "multi-layer thin coating" (5-6μm per coat), avoiding sagging and orange peel caused by excessive single-coat thickness. The flatness deviation between the touch-up area and the original paint is ≤2μm;
• Material Saving & Environmental Protection: The paint utilization rate reaches over 85%, requiring only 0.5mL of paint per 1cm² touch-up (1.2mL for traditional tools). Long-term touch-up can save 40% of paint costs, and with less paint mist, no professional ventilation equipment is needed.

(2) Built-In Precision Pressure Regulating Valve, Easy Pressure Control for Beginners

3. 125mL Mini Cup + Lightweight Design, Easier Operation

(1) Small-Capacity Cup, Eliminating Touch-Up Paint Waste

(2) 280g Ultra-Light Gun Body, No Fatigue in Long-Term Use

III. Application Scenarios (APPLICATION SCENARIOS)

1. Local Scratch Touch-Up in Auto 4S Shops (Core Scenario)

1. Pre-Treatment: Sand the scratch with 2000-grit sandpaper, cover the 1cm area around the scratch with masking film, install the 0.5mm nozzle, and pour 15mL of clear coat;
2. Precision Touch-Up: Keep the nozzle 6cm away, lightly press the trigger for spot spraying, apply 4 thin coats (3-minute interval between coats, 6μm per coat) to fully cover the scratch without edge blur;
3. Post-Treatment: After the clear coat dries, lightly polish with 3000-grit sandpaper, and clean the gun (rinse the nozzle with clear coat thinner, taking 1 minute).
   Result: The color difference between the touch-up area and the original paint is ≤ΔE1.0 (detectable by professional instruments, invisible to the naked eye), with no scratches or sagging. Customer satisfaction reaches 99%, and touch-up time is reduced from 1 hour with traditional spray guns to 20 minutes.

2. Mobile Phone Shell Touch-Up in Electronic Repair Shops (Scenario 2)

1. Pre-Treatment: Clean the chipped area with alcohol, mask the middle frame buttons and camera area with masking tape, install the 0.8mm nozzle, and pour 8mL of touch-up paint;
2. Local Touch-Up: Keep the nozzle 5cm away, apply 3 thin coats at 10cm/s (2-minute interval between coats), covering only the chipped area to avoid paint mist diffusion to other parts;
3. Finishing: After the touch-up paint dries, wipe the surface with a lint-free cloth, clean the gun, and store it.
   Result: The touch-up area has the same texture as the original middle frame (no difference in matte effect) with no unevenness to the touch. Customers mistakenly think "it was not repaired", increasing the repurchase rate by 80%.

3. Detail Touch-Up in Model Studios (Scenario 3)

1. Debugging & Preparation: Install the 0.5mm nozzle, pour 5mL of nitrocellulose paint, adjust air pressure to 27 PSi, and test atomization on a waste model part (to ensure fine particles);
2. Texture Repair: Use a magnifying glass for assistance, keep the nozzle 5cm away, and slowly spot-spray along the defective texture to restore the original model texture details, taking 8 minutes;
3. Cleaning & Maintenance: Rinse the gun body with model paint thinner, and soak the nozzle in thinner separately to avoid blockage.
   Result: The repaired texture is identical to the original model texture, with no misalignment or blurring. Customer satisfaction among model collectors reaches 100%, solving the pain point of "stiff textures" in traditional brush repair.

IV. Frequently Asked Questions (FAQ)

Q1: "Edge blur" (uneven transition between the touch-up area edge and the original paint) occurs during touch-up. How to solve it?

1. Air Pressure Adjustment: Reduce the air pressure from 29 PSi to 27-28 PSi (ultra-low pressure reduces paint mist diffusion), fine-tune via the gun's pressure regulating valve, and test atomization until it shows a "narrow fan shape with no peripheral scattered particles";
2. Nozzle Distance Control: Shorten the nozzle distance to 5-6cm (distance ＞8cm easily causes blur), and use "spot spraying transition" along the edge of the touch-up area instead of continuous spraying;
3. Paint Dilution: If blur persists, add 5% dedicated thinner to reduce paint viscosity (e.g., car clear coat thinner for car clear coat) to improve paint leveling and achieve natural edge transition.

Q2: The 125mL cup capacity is too small, requiring frequent refueling for large defects (e.g., local paint chipping on car bumpers, area 5cm²). What to do?

1. Pre-Prepare Paint: Calculate the required paint amount in advance (approx. 30mL for 5cm² touch-up), prepare it in a small measuring cup at once, and pour it into the cup in 2 batches (15mL each) to avoid color difference caused by frequent dilution;
2. Accessory Expansion: Contact the merchant to purchase a "series connector" for 125mL cups, which can connect 2 125mL cups in series (total capacity 250mL) for medium-area touch-up (5-10cm²) without affecting gravity feeding stability;
3. Operation Skill: Spray the edge transition layer first, then fill the middle area to reduce paint waste—one refueling can cover a larger area.

Q3: When using the 0.5mm nozzle for touch-up, the nozzle is frequently blocked (no paint sprays out). What is the reason?

1. Paint Filtration: Filter the paint through a 300-mesh sieve before touch-up (especially car paint containing metal pigments) to remove impurities and particles, avoiding blockage of the ultra-fine nozzle;
2. Cleaning Frequency: Rinse the nozzle with dedicated thinner every 10 minutes of touch-up (squeeze the trigger to let the thinner flow through the nozzle) to prevent paint from drying and hardening inside the nozzle;
3. Nozzle Maintenance: Gently unclog the blocked nozzle with the included 0.3mm needle (do not use excessive force to avoid scratching the nozzle inner wall), and rinse with thinner 3 times before use after unclogging.

Q4: Can a household rechargeable air compressor (0.1m³/min) be used? Will it affect touch-up precision?

1. Small-Area Touch-Up (e.g., mobile phone paint chipping, model repair): A 0.1m³/min air compressor can support 0.5/0.8mm nozzles. Fully charge the battery and use the "10s spraying + 5s pause" intermittent mode to avoid air pressure drop (pressure below 27 PSi will cause poor atomization);
2. Medium-Area Touch-Up (e.g., small car scratches): It is recommended to replace with a 0.15m³/min air compressor. Otherwise, unstable air pressure will cause "uneven atomization", leading to color difference or uneven thickness in touch-up;
3. Adaptation Suggestion: When choosing an air compressor, prioritize "continuous output pressure ≥29 PSi" over displacement alone to ensure stable air pressure during touch-up and guarantee precision.
