Penetrol Anti-Rust Control

Penetrol makes it easy to control rust

What makes rust?

Ordinary paint and primers "bridge" over the small imperfections found on any metal surface. Under this "bridge" air is trapped. Air contains moisture and this mixture of oxygen and hydrogen forms iron-hydroxide i.e. rust. Take one of them away and you eliminate rust. Under a microscope rust looks like a sponge full of air. Penetrol, due to its low surface tension will penetrate all the way through this sponge driving out the air and moisture and completely saturate the rust right down to the unattacked iron or steel. It has literally taken away the "food" rust needs to form and, by turning the existing rust into a protective coating, further rust formation is stopped and the paint is assured of 100% contact with the metal surface, the most important requirement for effective metal protection.

Penetrol works and that's why it is used and recommended by people working in the roughest environment of all, the world's major shipping companies.

Use Penetrol on structural steel, cast and wrought iron, wire fences, cars, trucks and trailers, corrugated iron, garden tools, tanks and anything made from ferrous or non-ferrous metal. Penetrol flows easily into crevices, welding seams, pipe joints and other areas that are hard to reach by brush, such as the inside of car doors.


When Penetrol was applied to this steel joint at point A, it penetrated between the surfaces of the joint to emerge at points B and C, protecting the joint against further oxidation.

Remember: If you can't reach it - you can't fix it.

Penetrol makes it easy to stop and prevent further rust

This is how easy it is to use Penetrol. Just saturate the rusted surface with Penetrol until it has a shiny appearance. When dry, continue with any oil, alkyd or water based paint. The main thing to remember about treating rust is that if you can't reach all areas of all surfaces, you're ultimately wasting your time.

Application guide

Light rust and new steel: 1 part primer, 2 parts Penetrol. Heavy rust: Penetrol surface until it has a shiny appearance. NOTE: Aluminium Penetrol makes an excellent top coat for iron roofs, metal fences, factory ceilings, tanks etc.

There is no need to remove tightly bonded rust

Penetrol makes it easy to restore corroded brass or copper and bring back lustre to chrome & aluminium. Scrub surface with fine steel wool soaked with Penetrol to loosen corrosion and dirt. Wipe surface with a rag after 5 minutes, then polish with a soft cloth.

To remove rust stains from chrome scrub with fine steel wool and Penetrol. Then wipe chrome with a soft cloth to restore shine. The Penetrol will remain in the pits stopping further rusting.

Penetrol makes it easy to restore vinyl car roofs and other plastics

Clean plastic with mild detergent. Rinse and let thoroughly dry. Apply a generous amount of Penetrol and after 5 minutes wipe off the excess. Polish with a soft cloth. Avoid application in direct sun light. Use same method for dashboards, plastic bumpers etc.
