The Mipa Monofil Bridging Filler is designed for automotive technicians and automotive restoration enthusiasts who need a reliable solution for repairing structural damage, holes, and deep surface imperfections. Its key benefit is the high structural strength provided by its glass-fibre reinforced formula, which creates a durable, waterproof bond on various metal and synthetic surfaces. A notable caveat is that while it is robust and easy to sand, its rapid curing time requires users to work efficiently to achieve a smooth finish before the material hardens completely.

This filler is designed for metal and GRP. It is generally not recommended for flexible plastic bumpers, which require specialized plastic fillers.
Yes, once the filler is sanded smooth, it should be cleaned and primed before applying paint to ensure proper topcoat adhesion.
Always refer to the specific label on your tin, as ratios can vary by batch; typically, it is a small percentage of hardener by weight.
The filler itself is waterproof and prevents moisture from reaching the metal, but all rust should be removed before application to prevent corrosion from spreading underneath.
It is better to apply in thin, successive layers to ensure thorough curing, although its bridging properties allow for thicker applications than standard lightweight fillers.
Reduce the amount of hardener slightly, but ensure it remains within the manufacturer's recommended percentage range to maintain proper structural integrity.
Ensure the surface was sanded with coarse abrasive to create a 'key' and that it was thoroughly cleaned with a degreaser before application.
Before application, ensure the substrate is clean, dry, and free of oil or grease. Sand the surrounding area to improve mechanical adhesion. Mix the filler with the provided hardener according to the manufacturer's specified ratio, ensuring the mixture is a uniform color without streaks. Apply to the surface within the short pot-life window. Once cured, store the tin in a cool, dry place and ensure the lid is sealed tightly to prevent the filler from drying out. Avoid applying the filler in extreme heat, which will accelerate the curing time beyond the point of easy application.
