FAQs
Can this filler be used on plastic bumpers?
Yes, it is compatible with most plastics, but always test on a small, inconspicuous area to ensure proper adhesion.
What sanding grit should I finish with?
Start with P80 for initial leveling and progress to P120 or finer for a smooth finish suitable for priming or painting.
Can I store the unused mix for later?
No. Once the hardener is added, the chemical reaction is irreversible. Only mix the amount you need for the immediate task.
Is it safe to use in a professional paint booth oven?
Yes, the product is stable and compatible with low-bake oven systems up to 90 degrees Celsius.
Does it need a primer after sanding?
Yes, it is recommended to apply a suitable primer over the filled area to ensure the paint finish is uniform and long-lasting.
Troubleshooting
Filler is not hardening after 20 minutes
Check the mixing ratio; if too little hardener was used, the reaction will be significantly delayed or fail. Also, ensure ambient temperatures are not significantly below 18 degrees Celsius.
Filler cracking after sanding
This often occurs if the filler was applied too thickly in one pass or if the surface was not properly cleaned and degreased before application.
Pinholes appearing on the surface
Avoid over-mixing the filler. Fold the hardener into the filler to minimize trapped air bubbles during the preparation phase.

Setup, Compatibility & Care
To ensure the best performance, always clean and degrease the repair surface before application. Mix the filler with the provided hardener using a strict ratio of 100 parts filler to 2 parts hardener. Once mixed, apply promptly as the material will begin to react. Avoid placing any unused, mixed paste back into the original tin, as this will contaminate and harden the entire contents. Store the tin in a cool, dry place away from direct sunlight to extend its shelf life. Always ensure the lid is sealed tightly after every use.
