Tetrosyl Color Cure 2K Fibrofil Paintwork Glass Fibre Car Body Dent Filler - 2L X4

The recommended mixing ratio is 100 parts filler to 2 parts hardener. Always measure accurately.

At 20 degrees Celsius, the filler can be sanded after approximately 20 minutes.

This product is designed for metal and glass fibre surfaces. For plastic bumpers, a specific plastic filler may be more appropriate.

The optimal sanding time is achieved at 20 degrees Celsius. Curing times can vary with ambient temperature.

Yes, it is suitable for low bake oven systems operating at 80°C to 90°C.

Store in a cool area, away from frost. Keep paste cool in summer and warm in winter if needed.

The glass fibre provides enhanced toughness and vibration resistance to the repair, making it more durable and less prone to cracking.

Ensure the correct ratio of hardener to filler (100:2) has been used. Check the ambient temperature; if it's too cold, curing will be slower. Try to work in conditions closer to 20°C. Ensure hardener is not expired.

Too much hardener may have been used, causing premature and excessively hard curing. Ensure accurate measurement for future applications. If already applied, use a coarser grit sandpaper (P80+).

The surface was not properly cleaned or prepared before application. Re-clean the area thoroughly with Tetrosyl Compliant Panel Wipe and reapply the filler. Ensure the surface is dry.

This could be due to excessive shrinkage caused by too much hardener or applying the filler too thickly in one go without proper support. Ensure correct mixing ratios and consider building up thicker repairs in layers, allowing each to cure partially.
