  2. 4941 - any good? 5 Star Review

    Posted by on 21st Oct 2020

    Dinitrol 4941 is an excellent product .Using the aerosol version, it is easily applied and adheres well to external chassis surfaces, Care should be taken to avoid contact with the eyes or skin during application (use gloves and eye protection) and it is best applied either in a workshop or on a calm, non - breezy day if working outside. It has a fairly strong odour during application but this is not noticeable afterwards. Over a period of ten years I have used 4941 to protect a Land Rover chassis with re - applications being made every two or three years. The chassis surfaces have remained well protected and corrosion free. Although it is a fairly expensive product, it is extremely good and I can confidently recommend it..

  3. Dinitrol Underbody Wax 5 Star Review

    Posted by on 7th May 2020

    I bought this product to maintain the full chassis Dinitrol undercoating that I had previously had sprayed onto my Land Rover within the first few months of ownership. So after a few years some small areas were showing slight surface rust and I needed to tackle these.
    This product is easy to use and very easy to spray leaving a nice professional even coating. I would recommend dinitrol to anyone looking to extend the life of their chassis.
