Yep - the first one - looks just like an Aldi one only yellow - but the Aldi ones were a tenner! Surely they must be cheaper somewhere?

When painted on it seemed to sit on the surface of our rust rather than soaking in and reacting. It also took longer to dry, meaning we had to wait until the next day until we could paint over it with our primer and top coat. One side of the steel sample was left unpainted while the other was sprayed with a single coat of primer and acrylic top coat, replicating a typical DIY repair. Once dry, the samples were then doused daily in salty water for four weeks to encourage any corrosion to reappear. We then scored them on ease of use, rust-resisting performance and price. Verdict

Once the primer is dry, you can continue to repaint the surface.Before you can use the rust converter, you need to brush off the rust with either a wire or a brush. By doing so, you will allow the product to react better with the rust. When the rust converter reacts with the rust, it forms a durable compound that is also stable. It takes less than twenty minutes for the reaction to begin. This is a two-in-one product that works as both a rust converter and a primer. It features a unique system for controlling corrosion, which was developed by Bayer-Wood Technologies. It is very effective when it comes to eliminating rust from metal surfaces. However, it is only designed for ferrous metals and nothing else. It can, therefore, be applied on boats and yachts as it has been tested for salt sprays. Other areas of application include gates, hinges, wheels of cars, and doorways, among others at home.
