Complete Paint Polishing Workflow
Professional-grade paint correction using J2 Water-Based Polishing Compound
Tools Required
- J2 Water-Based Polishing Compound
- Rotary (RO) polisher
- Wool pad (heavy cutting) + foam pad (fine finishing)
- Microfiber towels
- Painter's tape and masking film
Step-by-Step Instructions
Preparation & Paint Inspection
Park the vehicle in a shaded area and wait for the paint temperature to drop to 15-25°C. Perform a thorough wash to remove surface dust and dirt. Use masking film to protect badges, headlights, rubber seals, and other sensitive areas. Use a bright light or flashlight to closely inspect the paint surface, recording the distribution of scratches and oxidation to determine work areas and cutting intensity.
Select the Right Polishing Pad
Choose the pad based on paint condition: 1) Wool pad — for removing scratches, oxidation, and heavy defects with strong cutting power; 2) Coarse foam pad — for moderate defects and removing fine scratches left by the wool pad; 3) Fine foam pad — for final polishing and gloss enhancement. Mount the pad securely on the polisher, ensuring firm attachment.
Product Dispensing & Pre-Distribution
Dispense approximately 5-8g (coin-sized) of J2 Water-Based Polishing Compound and spread evenly on the pad surface. Place the pad lightly on the paint, start the polisher at 1500-1800 RPM and idle for 2-3 seconds to distribute the product evenly across the pad. This step avoids direct high-speed contact with the paint surface.
Section-by-Section Polishing
Work in 60cm × 60cm sections. Apply moderate pressure with the polisher on the paint surface, moving in a cross-hatch pattern or with 50% overlap. Keep the polisher parallel to the paint surface, avoiding tilting. Spend 20-40 seconds per section before moving to the next area.
Inspection & Spot Treatment
After completing a section, gently wipe with a clean microfiber towel and inspect the polishing result. Observe the paint gloss and scratch removal. For remaining light scratches, switch to a finer foam pad and repeat. Stubborn scratches may require multiple passes, but monitor total material removal carefully.
Cleanup & Residue Removal
After completing the full vehicle polish, rinse thoroughly with clean water to remove all polishing residue. Dry the paint with microfiber towels. Check for any remaining polish or wax residue, especially at edges and body lines. Use a wax remover for final cleaning if needed, ensuring the paint surface is completely clean.
Protection & Finishing (Optional)
After polishing, the paint should be protected: 1) Use J5 Mirror Finish Restorer for fine finishing and gloss enhancement; 2) Professional users can apply a sealant or ceramic coating. Apply the protection product evenly, allow to dry, then buff with a clean towel to a mirror finish.
Final Inspection & Cleanup
Perform a final inspection under good lighting conditions. Confirm all target areas have reached the desired result. Remove all masking film. Clean the workspace and return tools to their places. Record the process and results. Avoid rain or car washing for 48 hours to allow the protection layer to fully cure.
Important Notes
- Always test on a small, inconspicuous area before full-panel work
- Never exceed 40 seconds per section to avoid overheating and paint damage
- Wool pads have strong cutting power — beginners should practice with foam pads first
- Keep polisher speed at 1500-1800 RPM — higher speeds can cause new scratches
- Deep scratches (primer exposed) require touch-up paint first, not just polishing
- Ensure ventilation during work, wear safety glasses and a mask
Daily Paint Care Routine
Quick deep care using J1 3-in-1 Cleaning Wax
Tools Required
- J1 3-in-1 Cleaning Wax
- Microfiber towels
- Foam applicator pad (optional)
Step-by-Step Instructions
Preparation
Wash the vehicle clean and dry thoroughly. Ensure the work environment is shaded and well-ventilated, away from direct sunlight. Mask sensitive areas if needed. Have all tools and materials ready.
Product Dispensing & Pre-Distribution
Apply a coin-sized amount of J1 onto a towel or sponge. If using a towel, spread the product evenly across the surface; if using a foam pad, distribute evenly on the pad. First-time users should test on a small area first.
Even Application
Using circular or cross-hatch motions, apply J1 evenly across the paint surface. Maintain moderate pressure to ensure the product contacts the paint thoroughly. Use approximately 5ml per section.
Buffing to Shine
After the product dries (forming a uniform haze), use a clean microfiber towel to buff the surface. Wipe horizontally first, then vertically, until the paint shows a glossy finish. Repeat wiping if there is visible residue.
Inspection & Spot Treatment
After completing the full vehicle, inspect under good lighting. Areas with remaining imperfections can be re-treated. Stubborn stains may benefit from more product and longer dwell time.
Final Cleanup
Use a clean towel for a final wipe across the entire vehicle, ensuring no product residue remains. Use another clean towel for a shine-enhancing pass. For extra gloss, apply a thin second coat after full drying and buff quickly.
Important Notes
- J1 is a 3-in-1 product — no separate polishing or protection step needed
- Recommended usage: 1-2 times per month for best results
- Not suitable for interior surfaces, glass, leather, or rubber trim
- For severe scratches and oxidation, use J2 first then follow with J1 for maintenance
Quick Shine Process
Mirror finishing using J5 Mirror Finish Restorer
Tools Required
- J5 Mirror Finish Restorer
- Microfiber towels (2-3)
Step-by-Step Instructions
Preparation
Ensure the vehicle has just been washed and the paint surface is clean and fully dry (wait 10-15 minutes after washing). Work in a shaded area, away from direct sunlight. Have J5 Mirror Finish Restorer and microfiber towels ready.
Product Application
Squeeze J5 Mirror Finish Restorer and apply a moderate amount onto a fine foam pad. Use a polisher at low speed (600-800 RPM) for even application. Keep the coating thin and uniform, working in sections.
Quick Buffing
After application, wait 1-2 minutes (adjust based on ambient temperature). Use another clean microfiber towel in a cross-hatch wiping pattern. First use the folded towel's large surface for initial wiping, then unfold for a fine buffing pass until the paint shows high gloss.
Final Inspection
Inspect the full vehicle gloss under good lighting. Any missed areas can receive a quick touch-up buff. For details like wheels and badges, use cotton swabs or a small towel.
Important Notes
- X1 has a fast-acting formula — results visible in 5-10 minutes after application
- Never apply in direct sunlight or on hot paint surfaces
- Apply a thin coat — excess product won't improve results but makes buffing harder
- Use after every wash to maintain continuous shine
- Not suitable for removing visible scratches — deep scratches require polishing first
Glass Oil Film Removal Process
Restore clear visibility using J10 Glass Polishing Compound
Tools Required
- J10 Glass Polishing Compound
- Glass-specific polishing pads (#3 coarse, #2 medium, #1 fine)
- Rotary polisher
- Painter's tape and masking film
- Glass cleaner
- Microfiber towels (at least 3)
Step-by-Step Instructions
Preparation & Masking
Park in a shaded area with glass surface at 15-25°C. Use masking film and tape to protect window frames, wipers, rubber seals, and badges. Pay special attention to protecting wiper blades — polishing compound will damage them.
Clean the Glass Surface
Thoroughly clean the glass with a glass cleaner to remove dust, sand, and other particles. Rinse with water and dry. This step is critical — residual hard particles will cause new scratches during polishing.
Product Application & Pre-Distribution
Apply glass polishing compound evenly on the glass surface. Start the polisher at low speed (approximately 1000 RPM).
Section-by-Section Polishing
Work in 30cm × 30cm sections. Start the polisher at 1000-1500 RPM. Move in circular or straight-line patterns to cover the area evenly. Spend 20-30 seconds per section before moving on. Keep the glass surface lubricated.
Inspection & Spot Treatment
After each section, wipe with a clean towel and inspect the result. For areas with heavy oil film, repeat 1-2 times. Pay extra attention to wiper mark areas.
Cleanup & Inspection
After completing all glass panels, rinse thoroughly with plenty of clean water. Use glass cleaner again to remove all polishing residue. Dry with clean microfiber towels.
Finishing & Protection
Remove all masking materials and clean edge residue. Apply a glass hydrophobic coating if needed for final protection. Avoid using wipers for 24 hours after treatment to allow the protection layer to fully cure.
Important Notes
- Limit each section to 30 seconds maximum to avoid glass overheating and distortion
- Deep scratches (can insert a paper slip) cannot be fully repaired — glass replacement needed
- Keep the glass lubricated during polishing — dry grinding causes over-polishing
- Use with caution on tinted or coated glass — may damage existing coatings
