FAQs
Can I apply this over rust?
It is highly recommended to remove as much loose rust as possible before application to ensure the coating adheres to sound metal.
Is this paintable?
The product is designed to provide a finished black protective layer, though compatibility with specific topcoats should be tested on a sample area first.
How much does one 1-litre canister cover?
Coverage depends on the thickness of the application, but one 1-litre canister is typically sufficient for localized touch-ups or specific wheel arch treatments.
Do I need special equipment to apply it?
Yes, this product is designed for use with an underbody spray gun that attaches to the canister.
Does it require a primer?
For bare metal surfaces, using an appropriate automotive primer before the Schutz coating can enhance long-term corrosion protection.
Is this product suitable for use inside the car cabin?
No, this product is specifically formulated for external underbody and chassis protection.
Troubleshooting
Coating is peeling or flaking off
Usually caused by poor surface prep; remove loose coating, clean thoroughly with degreaser, and re-apply.
Inconsistent texture during spraying
Adjust the air pressure on your spray gun or check that the nozzle is not partially clogged.
Slow drying time
Ensure the application area is well-ventilated and within the recommended temperature range (typically above 15°C).

Setup, Compatibility & Care
To achieve professional results, ensure the vehicle surface is completely clean, dry, and free of oil, grease, or loose rust. Use a degreaser if necessary. It is recommended to mask off areas like brake components, exhaust systems, and moving parts before application to avoid over-spray. Once applied, the product requires adequate drying time in a well-ventilated area before exposing the vehicle to road conditions. Maintain the coating by periodically inspecting for deep gouges or areas where the metal may be exposed, cleaning those spots, and performing a localized re-application as needed.
