UNITOR is promoting anti-rust products as a ''first aid'' measure for controlling rust onboard ships. The company has introduced two rust-stabilising primers for areas onboard ship that can be reached by conventional painting and two corrosion inhibiting aerosol sprays for other areas that cannot. The rust-killers have been developed to provide ship crews with a quick and effective solution to the never ending problem of shipboard corrosion. The products have been designed to reduce the time and effort spent on re-painting so that the crew's time can be devoted to other activities. The anti-rust primer can be painted on to firmly adherent rust following the removal of all scale and loose rust, stabilising it for long term corrosion protection. Over the past two years Unitor's anti-corrosion systems have been used to control corrosion on over 600 vessels worldwide.
