Product Overview


Rust Mechanic™ has been designed to meet the needs of the future. This state of the art rust converter is performance oriented and environmentally compliant.

Rust Mechanic™ instantly bonds with rust, stops its growth, transforms it into a non-rusting paintable surface, and prevents future rust formation.

Rust Mechanic ™ is a rust converter designed to be directly applied to rusty surfaces to convert residual rust on steel surfaces to a harmless and adherent Ferrous chemical compound.

Rust Mechanic  works by means of a chemical reaction which transforms rust into a dark, inert protective polymeric coating that seals out moisture. It provides a superior primer coating on rusty steel and iron for the application of oil based paints.

Rust Mechanic ™ the best rust converter NZ loves!

Unlike standard scrape, prime and paint regimes, the user does not have to bring the surface down to bare metal to achieve good results.

Once the coating is allowed to dry, typically overnight, it should be top coated with GilsoFlex™, ClimoPlate or other quality oil based paints.

Rust Mechanic  will extend the life of rusted iron parts. It’s less expensive and less time consuming than traditional methods.

    Product works well. Very easy to apply and seems to soak into the rust and cover it with a waterproof layer. I am sure that once painted over this, it will no longer rust in the same area.
