FAQs
Does this product work on rusted surfaces?
It provides a protective barrier, but for best results, remove loose rust with a wire brush before application.
Can I paint over this sealant?
Tetroseal is designed as a finish coat; it is not recommended to apply additional paint over the top of this sealant.
How long does the drying process take?
It should be touch dry in a few hours, but allow 24 hours for a full, durable cure before exposing the vehicle to road conditions.
Is this product heat resistant?
It is intended for general underbody use and should not be applied to the engine block or the exhaust system.
How many cans do I need for a full car?
Coverage depends on the vehicle size, but typically 2-4 cans are required for a thorough application on a standard passenger car.
Troubleshooting
Spray nozzle is clogged
Turn the can upside down and spray for 5 seconds to clear the nozzle, or soak the nozzle in warm soapy water.
Sealant is peeling or flaking
This usually indicates the surface was not clean or dry enough during application; remove loose material and re-clean before reapplying.
Uneven or streaky finish
Ensure you are holding the can at a consistent distance (approx. 20-30cm) and using steady, sweeping motions.

Setup, Compatibility & Care
Before using the Tetroseal Aerosol, ensure the vehicle is parked on a flat, level surface and that you have adequate ventilation, preferably in a garage or outdoors on a non-windy day. Protect surrounding areas like brake discs, exhaust systems, and suspension springs with masking tape or newspaper to prevent unwanted overspray. After application, allow the product to dry fully for at least 24 hours before driving, especially in wet conditions. To maintain the protection, inspect the underbody annually and perform touch-ups on areas where the coating may have been scraped by road debris.
