Owatrol Oil penetrates through the rusted metal to the sound metal below, isolating it and protecting it from further rusting. Directly use on rusted surfaced – the penetrating oil drives out moisture and air and stabilises the metal to protect it from future damage. A bonding film is left on all surfaces Owatrol Oil is used on which maintains the natural look of the surface but allows enhanced adhesion, making it perfect as a foundation for primers or finishing coats. It gives excellent adhesion including on galvanised steel, aluminium, zinc, wood and more. Paint can be applied directly to firm rust when Owatrol Oil is used and is heat resistant up to +175°C.
