Product Information

Full details

Hammerite Waxoyl is an essential rustproofing solution designed for automotive enthusiasts and DIY vehicle restorers looking to extend the lifespan of their vehicle chassis, body panels, and internal cavities. By killing existing rust on contact and preventing new oxidation, this formula provides a long-lasting, flexible barrier that stands up to harsh environmental conditions, though users must note that the black finish requires careful application to avoid overspray on visible non-target areas.

FAQs

Can I apply Waxoyl over painted surfaces?

Yes, Waxoyl is safe to apply over painted body panels, but it is primarily intended for rust protection on metal surfaces, particularly underneath the vehicle.

Does it need to be thinned?

Generally, no. It is formulated to be used directly from the container, though warming it can help with flow.

How often should I reapply?

While it is long-lasting, it is recommended to inspect the chassis once a year and touch up any areas where the protective layer may have been abraded.

Can I use this on the engine block?

No, this product is designed for chassis, panels, and cavities and should not be used on hot engine components.

How do I remove it from skin or tools?

White spirit or a suitable degreaser is effective at cleaning tools and removing residue from skin.

Troubleshooting

Product is too thick to spray

Place the container in a bucket of warm water to soften the wax before application.

Uneven finish or drips

Apply in thin, multiple coats rather than one heavy application to prevent running.

Surface rust reappearing quickly

Ensure that heavy, loose rust scale was properly removed prior to application, as the wax cannot penetrate thick layers of loose rust.

Pros and Cons

Pros

  • Kills existing rust while preventing new corrosion
  • Remains flexible and will not crack or chip over time
  • Excellent resistance to water and road debris
  • Ideal for treating hidden internal cavities

Cons

  • Black finish is permanent and difficult to remove if applied incorrectly
  • Requires proper surface preparation for optimal adhesion
  • Can be messy to apply in confined spaces

Setup, Compatibility & Care

Before application, ensure that the metal surface is as clean and dry as possible; remove loose scale and dirt with a wire brush for best results. The product can be applied via a dedicated Waxoyl sprayer, a pressure pot, or a standard stiff-bristled brush for smaller areas. If applying in colder temperatures, warm the container in a bucket of warm water to improve flow and coverage. After application, allow sufficient drying time for the carrier solvents to evaporate, leaving behind the protective wax film. Store the container tightly sealed in a cool, dry place, away from direct sunlight or open flames.
