I have used this a lot in both of my buses. It can either be used on its own, or mixed with paint.

It’s great for sealing existing rust to prevent it from getting worse and also for preventing future rust.

Penetrol is an oil based product with a very low surface tension, which means when it’s painted onto the metal surface, it quickly spreads out and finds its way into every little crevice, preventing water and air from coming into contact with the metal.

I usually buy Penetrol at Bunnings, but you can also buy it online on Ebay.

I may earn a small commission from these links.
