Under Guard Paint

Simoniz Underguard offers a durable, protective finish for the underside of your car, protecting against rust, stone chips, salt, moisture and more. Delivered in an easy-to-use spray bottle, Black Underguard helps to preserve the integrity of components that are most at risk from daily wear and tear.

As well as corrosion and wear and tear, our car underbody protection spray also protects against extreme temperatures. Perfect for spraying components under your car, including exhausts, the product forms a heat-resistant coating to ensure that every part of the undercarriage is protected from rust and wear.

Any existing rust should be treated before application, as coating over rust may allow corrosion to continue beneath the surface. Avoid applying to braking components, moving parts, or rubber bushes. Use in a well-ventilated area and wear appropriate protective equipment.

Whatever the conditions and however old your car, Simoniz Underguard offers mile after mile of protection, providing an important line of defence that can help to protect against rust, wear, cracks and pitting when applied correctly. Underguard is part of our Paint and Maintenance Range, developed in the lab and tested on the road to give you the protection and professional results you need every day.
