The Tetrosyl UltraSmart 2K Fibrofil is an essential tool for professional automotive technicians and advanced DIYers looking to bridge holes and reinforce damaged body panels. This glass-reinforced, two-pack polyester putty offers exceptional structural integrity and vibration resistance, making it ideal for restoring compromised metal surfaces. While its rapid curing time ensures efficiency in a busy workshop environment, users must be comfortable working quickly with a precise two-part mixing ratio to avoid premature hardening.

No, it is highly recommended to apply this filler to bare, clean, and degreased metal for the strongest bond.
For large holes, use aluminum mesh to bridge the gap before applying the Fibrofil to provide a solid base.
Once fully cured and covered with the appropriate automotive primer and topcoat, it is moisture-resistant.
You must mix 98 parts putty to 2 parts hardener paste.
Once the filler is sanded to the desired shape, you can apply your standard primer, followed by base coat and lacquer.
This product is designed for metal surfaces. It may not adhere correctly to flexible plastic parts.
The ambient temperature may be too low, or the hardener was not mixed thoroughly; ensure proper ratio and room temperature.
Avoid vigorous mixing; fold the hardener into the putty using a flat spreader to prevent trapping air.
The surface was likely not cleaned well enough; ensure all rust, dust, and grease are completely removed before application.
Before starting your repair, ensure the ambient temperature is near 20 degrees Celsius to maintain the manufacturer's specified cure time. Surfaces must be cleaned thoroughly with a degreaser and dried completely; any remaining rust must be removed mechanically.
Mixing requires a ratio of 98% Fibrofil to 2% hardener paste by weight. Use a clean plastic mixing board and a spreader to ensure an even consistency. Once the putty has reached the required shape and is sanded flat, it can be primed using standard automotive primer-surfacers. Clean all tools immediately after use with a suitable solvent, as the material becomes nearly impossible to remove once fully cured.
