The Pro Range Fibreglass Bridging Premium Body Filler is designed for automotive DIY enthusiasts and professional body shop technicians who require a high-strength solution for repairing rusted-out panels or large gaps. Its key benefit is the inclusion of reinforced glass fibres that provide superior structural integrity and a water-resistant seal that prevents future corrosion. The primary caveat is that this filler is intended for structural bridging and will require a thinner, finer finishing filler over it to achieve a perfectly smooth, show-quality paint surface.

No. You must remove as much loose rust as possible and treat the area before application to prevent trapped moisture from continuing to corrode the panel.
No, it is a structural bridging filler. Use it for the foundation, then cover it with a fine-grade finishing putty for the final smooth surface.
Depending on temperature, it is usually ready for sanding within 20 to 30 minutes. It should be hard to the touch and not drag on the sandpaper.
This product is formulated for metal bodywork. Using it on flexible plastic bumpers may lead to cracking; specialized flexible plastic repair kits are recommended for those components.
Yes, once sanded smooth, you must apply a high-quality primer-surfacer to seal the filler and create a uniform surface for your topcoat.
Ensure the correct ratio of hardener was mixed into the filler; if it remains tacky, remove the material and re-apply with a higher ratio.
The surface was likely contaminated with grease or wasn't sanded enough; clean the area with wax and grease remover and sand more aggressively.
This occurs when air is trapped during application; use a firm pressing motion with the spreader to force the filler into the surface.
Before application, ensure the repair area is free from wax, grease, and loose rust. Sand the surface with 80-grit paper to provide a 'tooth' for the filler to grab onto. Mix the filler with the provided hardener on a clean mixing board, following the manufacturer’s ratio—typically a small ribbon of hardener to a golf-ball-sized amount of filler. Apply using a plastic or metal spreader, working quickly as the product begins to set within minutes. Store the container in a cool, dry place with the lid tightly sealed to prevent the polyester resin from drying out or absorbing atmospheric moisture.
