  • FAST ACTING RUST CONVERTER: JENOLITE Rust Converter is a fast acting, water based formulation that chemically converts rust in to a stable surface and prevents further rusting by creating a barrier to water vapour, oxygen and carbon dioxide.
  • READY TO PAINT: Once treated, converts rust to a ready-to-paint surface, can be painted directly over using most modern paints, without the need for a primer.
  • LONG LASTING PROTECTION: Resists water vapour, oxygen and carbon dioxide, protecting treated areas for the long term.
  • EASY TO USE: Easy to use, simply spray directly onto rust and watch as it gets to work, transforming rust into a ready to paint black/purple surface. No need to rinse off or wipe, just leave to dry and the once rusted area is ready to paint.
  • CAN BE LEFT ON TREATED OR PAINTED: Once applied it can be left as is or repainted with either water-based or oil-based paint.
  • SIMPLE APPLICATION: Quick acting rust converter, reacts with rust to convert it to a stable compound within 15 minutes. 
  • COVERAGE: Approximately 6 to 8 square meters per Litre.
  • MADE IN BRITAIN

1. What is JENOLITE Rust Converter Trigger Spray used for?

JENOLITE Rust Converter Trigger Spray is a fast-acting rust treatment that converts rust into a stable, paintable surface without the need for a primer. It neutralises rust and seals the metal, providing long-lasting protection against moisture and corrosion.

2. How does it work?

The water-based formula reacts chemically with rust to form a tough, blue-black compound that stops further oxidation. This creates a sealed surface resistant to water vapour, oxygen, and carbon dioxide — the main causes of corrosion.

3. What makes the trigger spray different from the standard liquid version?

The trigger spray applicator provides quick, even coverage with minimal effort. It’s ideal for larger areas or uneven surfaces and allows for easy application without the need for additional tools.

4. Do I need to apply a primer after using it?

No. Once fully dry, the converted surface acts as a primed layer and can be painted directly with most water-based or oil-based paints.

5. How long does it take to work?

The rust converter reacts within 15 minutes, visibly turning the surface blue-black as it converts the rust. Allow at least 3 hours for full drying before applying paint.

6. Can I leave the converted surface unpainted?

Yes, you can leave it as is — the coating provides effective rust protection on its own. However, for the best long-term results and UV resistance, overcoating with paint is recommended.

7. How do I apply JENOLITE Rust Converter Trigger Spray?

  1. Prepare the surface: Remove grease, oil, loose paint, and flaking rust using a wire brush or steel wool.
  2. Shake well: Shake the bottle before use to ensure even mixing.
  3. Spray directly: Apply evenly over the rusted area. Work into corners and edges with a brush if needed.
  4. Wait for reaction: Leave for 15 minutes. The rust should turn blue-black as it reacts.
  5. Allow to dry: Let dry for at least 3 hours before applying paint.

8. What if the rust doesn’t change colour?

If the treated area does not turn blue-black within 30 minutes, reapply another coat to ensure full chemical conversion.

9. How much area does it cover?

Coverage is approximately 6–8 square metres per litre, depending on rust thickness and surface condition.

10. Can it be used on any metal surface?

It’s suitable for all ferrous (iron-based) metals such as car panels, machinery, tools, garden furniture, and gates. It is not suitable for use on aluminium, stainless steel, or galvanised metal.

11. Can it be applied over existing paint?

No. It must be applied directly onto rusted metal for the chemical reaction to occur. Always remove paint and loose rust first.

12. How soon can I paint over it?

Once the surface is dry — typically after 3 hours — you can apply your chosen topcoat. For best results, paint the same day.

13. What types of paint can be used afterward?

You can use both oil-based and water-based paints. JENOLITE Direct to Metal Paint or a similar protective topcoat is recommended for long-lasting protection.

14. What finish does it leave?

After treatment, the surface will appear blue-black with a matte finish. This indicates that the rust has been successfully converted and sealed.

15. Does it provide long-term protection?

Yes. The converted layer forms a durable barrier that resists water vapour, oxygen, carbon dioxide, and even bacterial growth, preventing rust from returning.

16. Can it be used outdoors?

Yes. It’s ideal for both indoor and outdoor use, offering excellent weather and chemical resistance once cured and painted.

17. What precautions should I take during use?

  • Always wear gloves and eye protection.
  • Apply in a well-ventilated area.
  • Avoid contact with skin and surrounding paintwork (may cause staining).
  • Do not use in freezing conditions or direct sunlight.

18. How should I clean tools and equipment after use?

Wash brushes, nozzles, and tools immediately in clean water. Do not return excess product to the bottle.

19. How should I store the product?

Keep tightly closed in a cool, well-ventilated place between 5°C and 15°C. Protect from frost and direct sunlight.

20. Where is it made?

JENOLITE Rust Converter Trigger Spray is Made in Britain, maintaining the trusted quality and performance JENOLITE has been known for since 1939.

Remove all traces of oil or grease. Remove old paint and loose rust with steel wool or wire brush. Always check product compatibility. If in doubt test a small area first.

1. Apply directly to rust

Shake the bottle well, open the trigger spray to your desired formation and spray directly onto the rusted area. To ensure a full coverage, work well into any pitted areas, corners and edges using a brush. Ensure that exposed corners and edges are well-treated to avoid rust creep beneath.

2. Wait 15 minutes

Jenolite Rust Converter turns treated surfaces blue-black as it reacts with rust. IF AREA DOES NOT CHANGE COLOUR, RE-APPLY AFTER 30 MINUTES. No need to rinse off.

3. Ready to paint in 3 hours

Apply topcoat after minimum 3 hours. For best results paint same day.

4. Storage & reuse

Do not return excess Jenolite Rust Converter to the container.

Wash brushes and equipment in clean water immediately after use. Splashes onto surrounding paintwork and skin may cause staining - wash off immediately with water.

Keep container tightly closed. Store in a cool, well ventilated area. Avoid freezing and direct sunlight. Protect product from frost. Store between 5ºC and 15ºC.
