This very powerful product offers excellent protection against corrosion or rust. Tectyl comes from the well-known brand Valvoline and has been the most successful corrosion protector available for more than 75 years. Even if you are not a professional and are a real do-it-yourselfer, this spray is very easy to use. Tectyl Crystal Clear spray has many applications, including marine, automotive and even household and garden tools. This is partly due to the strong adhesive properties of the product. When applied, the spray forms a resin-based, colorless and corrosion-protective layer. The spray can also be used on electrical wiring, as it has very good moisture-repellent properties. The spray is available in a 0.4 liter bottle (Ref: 20055 Tectyl Glashelder 400ml).
