FAQs

Can I use this on plastic bumpers?

This kit is primarily designed for metal automotive bodywork; specialized plastic-specific fillers are recommended for flexible bumpers.

What is the mixing ratio?

Always refer to the specific technical label on the container, as ratios can vary slightly based on ambient temperature and humidity.

Can I paint directly over the filler?

No, you must prime the filler and stopper with an automotive-grade primer before applying color coats to ensure proper adhesion and leveling.

How long should I wait before sanding?

Curing times depend on ambient temperature, but generally, the filler can be sanded within 20-30 minutes at room temperature.

Does this kit include hardener?

Yes, standard hardener is typically included for both components to ensure they cure correctly.

Troubleshooting

Filler is curing too fast or too slow

Adjust the amount of hardener used. Too much hardener speeds up the process, while too little slows it down; use a strict ratio based on the manufacturer's temperature guidelines.

Surface feels tacky after sanding

The mixture ratio was likely incorrect or not blended thoroughly; remove the uncured material, clean the surface, and re-apply with proper mixing.

Adhesion failure

Ensure the panel surface is properly sanded with 80-grit paper to provide 'tooth' and is fully degreased before application.

Pros and Cons

Pros

  • Significantly lower weight compared to traditional heavy putties
  • Excellent featheredging properties for invisible repairs
  • Professional-grade adhesion on metal surfaces
  • Complete two-part system for deep and surface repairs

Cons

  • Requires precise measurement of hardener to avoid curing issues
  • Shelf life can be sensitive to storage temperatures
  • Requires basic proficiency in bodywork preparation techniques

Setup, Compatibility & Care

Before application, ensure the substrate is clean, dry, and free of rust or oil. Use a degreaser to prepare the surface. Mix the filler with the appropriate hardener on a non-porous mixing board using a plastic or steel spreader. Always work in a well-ventilated area and wear appropriate respiratory protection. After use, ensure lids are tightly sealed to prevent the product from drying out. Store the kit in a cool, dry place away from direct sunlight to maintain the integrity of the chemical properties.
