Product Information
Full details
The Tetrosyl Color Cure 2K Fibrofil is designed for automotive enthusiasts and professionals who need a durable, high-strength solution for repairing deep dents, rust holes, and cracks in metal or glass fibre panels. Its key benefit is a glass fibre-reinforced formula that provides superior structural integrity and vibration resistance, making it ideal for structural repairs where standard fillers might fail; however, users must be precise with the mixing ratio, as improper hardener usage can significantly impact curing time and bond strength.

FAQs
Can I use this on plastic bumpers?
This product is specifically designed for metal and glass fibre surfaces. It is generally too rigid for the flexible nature of plastic bumpers.
Do I need to prime after sanding?
Yes, you should apply a suitable automotive primer over the sanded filler before applying basecoat or topcoat paint.
Is it safe for low bake oven repairs?
Yes, the product is fully compatible with low bake oven systems operating at 80-90 degrees Celsius.
How should I store the tins?
Store in a cool, dry place away from direct sunlight. Ensure they stay warm in winter and cool in summer to maintain product integrity.
What is the recommended grit for sanding?
Use P80+ grade sandpaper for the initial shaping of the filler once it has cured.
Troubleshooting
Filler is not curing within the expected 20-minute window
Check the ambient temperature; if it is below 20 degrees Celsius, the curing process will slow down significantly.
Filler is hardening too quickly in the spreader
You may have used too much hardener. Ensure a strict 100:2 ratio and mix smaller batches if working in warm environments.
Poor adhesion to the metal surface
Re-clean the surface using a dedicated panel wipe to ensure no silicone, grease, or rust particles remain.
Pros and Cons
Pros
- Excellent structural integrity for bridging holes
- Highly vibration-resistant for long-term durability
- Fast drying time allows for quick turnaround on repairs
- Suitable for a wide range of automotive surfaces
Cons
- Requires precise mixing ratios for proper performance
- Sensitive to ambient temperature storage
- Hardener must be managed carefully to avoid application issues
Setup, Compatibility & Care
Before starting your repair, ensure the substrate is cleaned thoroughly with a product like Tetrosyl Compliant Panel Wipe to remove all contaminants, as oil or grease will cause adhesion failure. When mixing, adhere strictly to the 100:2 ratio; adding too much hardener will lead to premature curing or brittleness. Store the tins in a temperate environment—cool during the summer and warm during the winter—to ensure the shelf life and consistency of the paste. Never return mixed material back to the original container to prevent contamination.
