No Primer Rust Converter removes rust and provides a seal to prevent its return. The formula works by allowing 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. Jenolite’s Rust Converter Trigger Spray is tried and tested. It 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!
