This product is specifically formulated for metal surfaces and may not adhere properly to plastics.
For every 100g of putty, add 2g of hardener. It is best to use a digital scale for precision.
Yes, once fully cured, the filler provides a durable, water-resistant base for your paint system.
While you can apply primer directly, it is usually recommended to finish with a fine-grade body filler to smooth out the glass fiber texture before painting.
The Fibrofil is designed for minimal shrinkage, ensuring your repair remains level.
Check the hardener ratio. Ensure you are using exactly 2% hardener and that the ambient temperature is at least 20°C.
Mix the filler with a pressing motion rather than whipping it to prevent air entrainment.
Ensure you are using fresh P80 grit abrasive paper and that the product has not been allowed to over-cure for an extended period beyond the initial 20 minutes.
Preparation is critical for the long-term success of your repair. Always start with a clean, dry surface free of paint and loose corrosion. When mixing, adhere strictly to the 98:2 ratio of putty to hardener, mixing thoroughly while being careful to avoid folding air bubbles into the paste. The product is heat-resistant up to 90°C, making it safe for professional low-bake ovens. Store the containers in a cool, dry place and ensure lids are tightly sealed to prevent the product from drying out prematurely.
