Fernovus is used as a single product for the protection of metallic surfaces both indoors and outdoors. The product is applied directly to the rusted surfaces, even if they are slightly damp. It is not useful either to sand down or to apply anti-rust products or converters. The product contains neither chromium nor lead. Fernovus is a gel coating: it does not run and does not dribble. It is applied to bare or painted metal, zinc-coated sheets (only if very oxidized and free of grease), wood and cement. It is available in the following finishes: glossy, satin, mat, metallic, hammered, micaceous (see the shade on the lid).
