Owatrol Oil is available in an easy to use 300ml spray can, making it even easier to apply to hard to reach places. Owatrol Oil can be used directly on the rusted surfaces as it penetrates through the rusted metal to the sound metal below protecting it from further rusting. Owatrol Oil is colourless and can be used alone or adding to oil-based paints as a rust inhibitor. When used alone, as a rust inhibitor it provides a tough, flexible finish, driving out excess moisture and air, displacing it from rusted metal, so stopping rust dead in its tracks. Used alone on porous wooden surfaces, Owatrol oil will saturate and protect the wood from damage caused by moisture and prevent paint from peeling.
