How to Use

1. Prep the Surface: Sand the damaged area with sandpaper, making the sanding zone slightly larger than the crack or scratch. Wipe away all dust with a clean cloth.
2. Apply the Paste: Squeeze out an appropriate amount of paste and spread it in a thin, even layer using a small scraper. Avoid thick applications, as thicker layers may not dry fully. Work quickly — do not scrape back and forth repeatedly, as this can cause the coating to fluff, crack, or peel. Note: This product is suitable for scratches and surface damage under 0.5mm. For larger damage, fill with putty and sand before applying this paste.
3. Sand Smooth: After approximately 1 hour, use water-dampened sandpaper to smooth the repaired area. If any air bubbles or small scratches remain, repeat steps 2–3 until the surface is perfect.
