Jenolites No Primer Rust Converter allows surfaces to be painted over without the need for a primer by removing rust and providing a seal to prevent its return. 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. Other properties include good chemical and salt spray resistance. Our tried and tested Rust Converter provides a barrier to water vapour, oxygen and carbon dioxide and 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.
