Owatrol: the best rust preventative oil

(view more variants)


Owatrol is a rust inhibitor: it stops rust immediately and prevents new rust from developing.

It penetrates all the way into the healthy metal.

Another function that Owatrol has is that it insulates the substrate and expels moisture and air!

There are many uses for this rust preventative.

You can use it as a bonding layer, i.e. you can apply it directly to rust and the primer you apply will adhere well.

Can therefore be applied directly to non-loose layers of rust.

Second function as an additive to the paint.

Read the article about additive here.

Makes paints more fluid and easier to apply.

As a final application, it is extremely suitable for impregnating wood.

This makes the wood water-repellent.

See impregnation.


What is a great advantage is that it adheres to almost all surfaces: wood, zinc, aluminum, metal.

By adding as an additive you can continue working in almost all weather conditions; cold, warm, windy weather, of course not when it rains!

It also makes alkyd-based paints rust-resistant.

Another advantage is that it gives good covering power and that 1 layer is enough, provided the underlayers are good.


Suitable on all ferrous and non-ferrous metals, wood, plastic and even glass.

As an additive, you can add it to alkyd paints, alkyd-based stains, synthetic paints, urethane-based paints.

Not suitable for water-based paints and fast-drying paints (car paints).

Not even for rubber-based paints and two
component systems.

If you want to use the product as an anti-corrosion agent, use a ratio of owatrol and ¾ paint.

If you want to use it to make it more liquid, the ratio is add 5% to the paint.

I definitely recommend this product: your paintwork will last longer and you will never see rusty nails again!

Do you have a question about this?

Or have you come across another remedy that also works as effectively?
