More details

Cyndan Rust Buster penetrates the pores of the rust and bonds to the metal substrate beneath. It encapsulates and neutralizes the rust and forms a molecular bond with both the rust and the substrate. It dries clear, leaving a solid, pore-free surface which prevents further corrosion for up to 8 years.

Rust Buster is a clear drying environmentally friendly organic product and is comparatively safe to use. Rust Buster can be applied directly onto grossly rusted or clean metal surfaces with little to no surface preparation required.

Rust Buster alone will suffer ultraviolet degradation under sunlight being a non-pigmented protective coating. It is recommended you use Rust Buster Silver on all surfaces exposed to direct sunlight for extended periods as it has excellent heat reflection and UV resistance. It can be left in it’s final state or painted over with desired colour.

Rust Buster has excellent penetrating ability, gives excellent adhesion to oil free surfaces, remains flexible when dry, and has no odour once drying is acheived. Does not give off toxic fumes when welding, and when dry is virtually self extinguishing when the source of flame is removed.

Rust Buster will repair and protect marine vessels, steel roofs, silos, bridges, containers, structural steel, pipelines and can be applied to metals that are immersed in water (when overcoated with a suitable paint). It also acts as a rust preventing waterproof membrane when applied to new or non corroded metal surfaces.

Rust Buster can be used as an additive to oil based paints, if painting is required post treatment, and the surface can be painted without the need for a primer. Rust Buster can be mixed with any oil based paint, imparting many of its qualities including better film strength, reduced porosity and better longer lasting gloss. It also restores powder coated and painted metallic surfaces to their original sheen.

When used on faded paintwork it appears to reverse the oxidisation process, rejuvenating the colours of the paint. Can be made UV stable using Rust Buster Silver.

Rust Buster conducts heat readily when used on motor vehicle radiators, refrigeration coils, etc.


• Can be applied directly to rusted surface;
• Waterproofs the metal surface;
• Extends the life of the metal surface saving replacement costs.
