Product Information
Full details
Tetroseal Aerosol Underbody Sealant is designed for vehicle owners and DIY mechanics looking to protect their car's chassis and exposed metal components from the damaging effects of corrosion, road salt, and debris. This high-performance spray provides a durable, reliable barrier that helps extend the structural integrity of your vehicle's undercarriage. While it offers excellent coverage for hard-to-reach areas, users must ensure the surface is thoroughly cleaned and prepped beforehand, as the sealant will not adhere properly to existing rust or dirt buildup.

FAQs
Can I apply this over existing rust?
No, it is not recommended. You should remove any loose or flaky rust with a wire brush before applying the sealant for proper adhesion.
How long does it take to dry?
Drying times vary based on temperature and humidity, but generally, it is touch-dry within a few hours and fully cured within 24 hours.
Can I use this on exhaust parts?
No, this product is not heat-resistant and should not be used on exhaust systems or other components that reach high temperatures.
How many cans do I need for a full vehicle?
The quantity depends on the size of the vehicle and the desired thickness. It is usually best to keep at least 2-3 cans on hand for a thorough application.
Does it need a topcoat?
No, Tetroseal is a standalone protective sealant and does not require an additional topcoat.
Is it safe to spray near rubber bushes?
Avoid direct heavy application on rubber components, as some aerosols can cause certain types of rubber to degrade over time.
Troubleshooting
Spray nozzle is clogged
Remove the nozzle and soak in solvent or replace if a spare is available. Always clear the nozzle by spraying upside down after use.
Sealant is peeling or flaking off
This usually indicates the surface was not clean or dry enough during application. Scrape off the loose area, clean thoroughly with a degreaser, allow to dry, and reapply.
Sealant is running or dripping
The coat applied was likely too heavy. Apply thinner, multiple coats rather than one thick coat, allowing for drying time between applications.

Setup, Compatibility & Care
To ensure maximum effectiveness, the target area must be completely clean, dry, and free of any grease, oil, or loose debris. Use a pressure washer or degreaser to prepare the surface and allow it to dry fully before application. Shake the can vigorously for at least one minute before spraying. Hold the can upright and apply in smooth, sweeping motions. After use, clear the nozzle by turning the can upside down and spraying for a few seconds to prevent clogging. Store in a cool, dry place away from direct sunlight and heat sources to maintain the chemical integrity of the sealant.
