Jenolite No Primer Rust Converter removes rust, provides a seal to prevent its return and allows surfaces to be painted over without the need for a primer. No need to wipe clean, simply leave to dry and after just one application your metal will be suitable for over coating with most traditional paints. Provides a strong barrier to water vapour, oxygen and carbon dioxide and offers superb chemical and salt spray resistance. Our tried and tested formula also provides excellent resistance to bacterial growth. Jenolite Rust Converter does two jobs in one — it gets rid of the rust and converts the once rusted area into a stable surface, ready to paint, leaving the metal looking as good as new! Jenolite — the professional choice since 1939.
