How to Use

1. Prepare the Surface: Sand the damaged area with sandpaper, making sure to cover a slightly larger area than the crack or scratch. Wipe away all dust with a clean, dry cloth.
2. Apply the Paste: Squeeze out a small amount of paste and use a scraper to apply a thin, even layer over the damaged area. Avoid applying too thickly — a thick coat may not dry properly. Do not repeatedly scrape back and forth to prevent fluffing or cracking. Note: Suitable for scratches and gaps up to 0.5 mm. For larger gaps, fill with putty first, sand smooth, then apply this product.
3. Sand Smooth: After approximately 1 hour, lightly wet-sand the repaired area with damp sandpaper until smooth. Repeat Steps 2–3 if any air bubbles or minor scratches remain.
