JENOLITE Rust Converter Trigger Spray 500ml — Water-based, Low-odour Rust Neutraliser Ready to Paint

JENOLITE Rust Converter Trigger Spray is a water-based treatment that chemically converts active rust into a stable blue-black coating, stopping corrosion and leaving the surface ready to paint.

This 500 ml trigger-spray bottle is designed for busy DIYers and professionals who need a fast, low-odour method to stabilise rusted metal without grit-blasting or full mechanical removal. The formula reacts with iron oxide to form a protective layer that blocks water vapour, oxygen and carbon dioxide, helping to prevent further corrosion while allowing direct painting once dry. Because it’s non-flammable and water-based, it’s suitable for many indoor and outdoor metal repair tasks when used with basic PPE and ventilation.

How quickly does the converter work and what should I expect to see?

Jenolite’s converter typically changes the rusty surface to a blue-black colour within about 15 minutes, showing that the chemical reaction is underway. If no colour change appears within 30 minutes, a second application may be needed. Allow the treated area to dry fully—usually at least three hours—before overcoating with paint.

• Visible colour change to blue-black in ~15 minutes
• Reapply if no reaction after 30 minutes
• Drying time: minimum 3 hours before painting
• One 500 ml bottle covers roughly 3–4 m² depending on surface porosity

What surfaces and items can I use this spray on?

The spray is intended for ferrous metals affected by rust, including vehicle panels, garden furniture, gates, tools, machinery and metal railings. It works best on surfaces where loose scale, grease and flaking paint have been removed first. Do not use as a metal primer on non-ferrous metals without checking compatibility.

• Suitable for steel and iron components
• Common uses: gates, tools, machinery, car underbodies and railings
• Remove grease, loose paint and flaky rust before application
• Not formulated for aluminium or stainless steel without testing

How do I apply it safely and get the best protection?

Shake the bottle well, spray evenly over the rusted area and work into edges or pits with a brush if required. Wear gloves and eye protection, apply in a ventilated area, and avoid freezing temperatures or direct sunlight during application and drying. Because it’s water-based and low odour, there’s no need to rinse off; simply allow the treated finish to cure before painting.

• Shake bottle, spray evenly, brush into corners as needed
• Use in ventilated area, wear gloves and eye protection
• Non-flammable, low odour; no rinse required
• Store between 5 °C and 15 °C, keep container tightly closed

Will I still need a primer and how long does protection last?

After the converter has dried and formed its blue-black layer, most painted finishes can be applied directly without a separate primer—follow paint manufacturer guidance. The converted film creates a barrier against water vapour, oxygen and carbon dioxide, reducing conditions that drive further corrosion, but long-term protection depends on coating quality and environmental exposure.

• Paintable after full drying; primer often unnecessary
• Converted layer resists moisture and atmospheric gases
• Reapply treatment if conversion is incomplete
• Topcoat selection affects long-term corrosion resistance

Who is this for: JENOLITE Rust Converter Trigger Spray is ideal for homeowners tackling garden gates or outdoor furniture, vehicle hobbyists treating surface rust, and tradespeople needing a quick, reliable rust stabiliser before painting. It suits anyone who wants a low-odour, non-flammable, easy-to-use option to neutralise rust and prepare metal for a protective topcoat without heavy machinery or full metal replacement.
