The mixing ratio of hardener was likely too low. Always ensure a 98:2 ratio.
This is caused by trapped air. Apply the filler with firmer pressure and avoid over-mixing during the preparation phase.
The substrate was likely contaminated. Ensure the metal is completely clean, dry, and sanded to a rough texture for better mechanical bond.
Before applying the filler, ensure the vehicle panel is completely dry and free from contaminants like oil or wax. If rust is present, treat the metal with a rust converter first. The filler is compatible with most automotive paint systems, but it should always be topped with a suitable primer to seal the porous surface of the glass fibers. Store the containers in a cool, dry place away from direct sunlight to maintain the integrity of the polyester resin. Always ensure the hardener cap is tightly sealed after every use to prevent moisture contamination.
