Hi, Have you got gremlins in your electrics? We're not talking about small, mischievous creatures here but rather the problems that can be caused by the oxidised, green/blue corrosion you often see when connections have been exposed to moisture and the environment over time. This increases the contact resistance and can lead to intermittent electrical issues or complete failure, depending on the severity or the corrosion. Never fear though because help is at hand in the form of Contralube 770. Contralube is a clear gel that can be applied to all sorts of electrical contacts and connections and works by inhibiting moisture ingress and preventing corrosion - particularly useful in aggressive under-bonnet environments. Its silicone-free, does not evaporate over time and we think no toolbox should be without one! Priced at 17.40 (inc. VAT), it comes in a 25g tube (with nozzle for easy application), which is enough to do several multi-way connectors.
