How to Use

1. Prep the Surface: Sand the damaged area with sandpaper, making sure the sanding area is slightly larger than the crack or scratch. Wipe away all dust with a clean cloth.
2. Apply the Paste: Squeeze out an appropriate amount and spread it evenly with a small scraper in a thin layer. Avoid going back and forth repeatedly to prevent lifting or cracking. Note: This product is best suited for scratches and dents under 0.5mm deep. For larger damage, use a putty filler first, sand smooth, then apply this paste.
3. Sand Smooth: After approximately 1 hour of drying, use water-dampened sandpaper to smooth the surface. Repeat steps 2–3 if any air bubbles or imperfections remain.

Important Notes

• Actual color may vary slightly from images due to monitor settings and lighting.

Frequently Asked Questions

Q: Can I use the RayHong Fiberglass Repair Paste on deep cracks larger than 0.5mm?

A: For damage deeper or wider than 0.5mm, it is recommended to first fill the area with a standard putty compound and sand it smooth before applying this fiberglass repair paste as a finishing coat. This ensures a durable, professional-quality result.

Q: Do I need to mix this fiberglass repair paste with a hardener?

A: No! The RayHong Fiberglass Repair Paste is a single-component formula — no mixing or hardener is required. Simply squeeze the paste from the tube and apply it directly to the damaged area using a small scraper or applicator.

Q: How long does it take for the fiberglass repair paste to dry?

A: The paste typically dries in approximately 1 hour under normal conditions. Once dry, you can wet-sand it smooth. Apply in thin layers for best results, as thick applications may extend drying time significantly.

Q: Is this product suitable for car scratch repair as well as boat repair?

A: Yes! While it excels at fiberglass boat hull and deck repairs, this paste also works effectively on car scratch repair and other fiberglass surfaces such as RV panels and automotive body parts, making it a versatile tool for any fiberglass restoration job.
