FAQs
Can I apply this over existing rust?
While it seals the area, it is highly recommended to remove loose rust with a wire brush first for the best possible protection.
How many cans do I need for a full vehicle?
This depends on the size of your vehicle, but typically 3 to 5 cans are required for complete underbody coverage.
Is this safe for plastic trim?
The product is designed for metal surfaces; it is best to mask off any plastic components to avoid unwanted overspray.
How long does it take to dry?
Drying times vary based on temperature and humidity, but it is generally touch-dry within an hour and fully cured within 24 hours.
Does it need to be reapplied?
For optimal protection, it is advised to inspect the underbody annually and perform touch-ups in areas where the coating may have worn away.
Troubleshooting
Sealant is running or dripping during application
Apply thinner coats and increase the distance between the nozzle and the surface.
Sealant is not sticking to the metal surface
Ensure the surface is completely degreased and dry; any residual oil or moisture will prevent adhesion.
Nozzle becomes clogged during use
Remove the nozzle and soak it in a suitable solvent, or replace it if the blockage persists.

Setup, Compatibility & Care
To achieve the best results, ensure the undercarriage is completely dry and free from oil, grease, and loose rust before applying the product. Use a wire brush to remove existing corrosion if necessary. Shake the aerosol can vigorously for at least two minutes before starting. Hold the can approximately 20-30 cm from the surface and apply in light, overlapping passes. Allow sufficient drying time between coats to prevent sagging. Always use this product in a well-ventilated area, preferably outdoors or in a garage with the door open, and wear appropriate personal protective equipment, including gloves and a mask. After finishing, clear the nozzle by turning the can upside down and spraying until the propellant comes out clean.
