FAQs
How much area does a 500ml can cover?
Coverage depends on the number of coats applied and the condition of the surface. On average, a 500ml can may cover approximately 1-2 square meters.
Can I apply this over existing rust?
It is best to remove loose rust before application for optimal performance. Light surface rust can be covered, but significant rust should be removed.
Is this product suitable for use on exhaust systems?
No, it is not recommended for use on exhaust systems as it is not designed to withstand high temperatures.
How long does the coating last?
The longevity of the coating depends on environmental conditions and usage. Typically, it can last for several years with proper application and maintenance.
What is the best way to clean the nozzle?
After use, turn the can upside down and spray until only propellant comes out. If the nozzle clogs, clean it with a solvent.
Can I paint over the underbody seal spray?
Generally, it is not recommended to paint over the underbody seal spray. The rubberized formulation may not provide a suitable base for paint adhesion.
What safety precautions should I take?
Use in a well-ventilated area, wear appropriate safety equipment, including gloves and eye protection. Avoid inhalation of vapors.
Troubleshooting
Spray nozzle clogs during application.
Wipe the nozzle after each use. If clogged, clean with a solvent or replace the nozzle.
Sealant runs or drips during application.
Apply thinner coats and ensure the can is held at the correct distance from the surface.

Setup, Compatibility & Care
- Preparation: Clean the surface thoroughly, removing any loose rust, dirt, or grease. Use a wire brush or abrasive pad to remove any loose rust. Ensure the surface is dry before application.
- Application: Shake the can well before use. Apply the spray in even coats, holding the can approximately 20-30 cm from the surface. Multiple thin coats are better than a single thick coat.

- Care: Avoid contact with fuel and solvents. Clean any spills immediately. Inspect the coating periodically for damage and reapply as needed.
