Full details

The Tetrosyl Stonechip protective coating is designed for automotive enthusiasts and professional mechanics looking to safeguard lower vehicle body panels from road debris and corrosion. This durable, flexible formula provides a robust barrier against stone chips while doubling as an effective sound-deadening agent for wheel arches and under-chassis areas. While highly effective at rust prevention and impact resistance, users should note that this product is not compatible with synthetic painted surfaces, requiring careful surface preparation before application.

FAQs

Can I apply this over existing paint?

It is not suitable for use on synthetic painted surfaces. It is best applied to bare metal or properly prepped surfaces.

Does this product provide sound insulation?

Yes, it features excellent sound-deadening qualities, making it ideal for application inside wheel arches.

How long do I need to shake the can?

You must shake the can thoroughly for a minimum of two minutes before use to ensure the correct consistency.

What tools do I need to apply this?

This product requires a screw-top under-coating gun and an air compressor set to 40-80 p.s.i.

Can I paint over the stonechip coating?

Yes, once the coating is fully cured, it may be overcoated with compliant refinishing paint systems.

What is the recommended spray distance?

Maintain a distance of 30-45 cm from the surface for an even application.

Troubleshooting

Coating not sticking to the metal surface

The surface likely contains residue or oil; ensure you have thoroughly degreased the area with Tetrosyl Panel Wipe before re-applying.

Spray gun is clogging during application

Ensure the can was shaken for the full two minutes and check that the gun nozzle is free of debris. If the issue persists, check that your air pressure is set between 40-80 p.s.i.

Coating is peeling off shortly after application

This often indicates that the product was applied to a synthetic surface, which is not compatible. Ensure the substrate is bare metal or a compatible primed surface.

Pros and Cons

Pros

  • Excellent sound-deadening properties
  • Highly resistant to chipping and mechanical impact
  • Easy to apply with standard under-coating spray equipment
  • Can be painted over once cured
  • Provides a critical layer of anti-corrosion protection

Cons

  • Not suitable for use on synthetic painted surfaces
  • Requires professional under-coating spray gun equipment
  • Strict surface preparation (degreasing) is essential for adhesion
  • Limited to specific substrates

Setup, Compatibility & Care

To ensure maximum durability, the surface must be free of dust, moisture, and oil. Begin by cleaning the area with a high-quality degreaser. The product is intended for use with a pressurized under-coating gun. Before beginning the main application, verify that your spray nozzle is clean and free of dried material from previous uses. Once applied, allow the product to reach a full cure before attempting to apply any refinishing paint systems over the top. Store the cans in a cool, dry place and ensure lids are tightly secured to prevent premature curing or thickening.
