Rust Prevention - MK1, MK2 and MK2.5

As most of you reading this page will know, the Mazda MX5 are quite vulnerable to rust.

In the UK we use salt and other corrosive products on our roads during the winter montsh to deal with black ice and snow. These products help the metal in the sill and chassis rail area to rust. Mk2.5 and occasionally Mk2 cars tend to suffer from chassis rail issues.

The can be expensive to rectifying the damaged caused. Sometimes it makes the car almost uneconomic to repair!

In order to avoid these repair bills or at least delay them for an extended period, we offer an underseal service.

The service takes your car, removed all of the plastics on the underside and treats the areas that are most vulnerable and expensive to repair. In simple terms the body of the car not those parts than can be removed and changed easily.

We would not for example treat the car's sub-frames and wishbones as these are replaceable and made from metal that would be expected to last. There are cars on the road toady with wishbones and subframes over 30 years old!

After we have cleaned the road grim off the car, we check all of the original Mazda underseal for crackes, remove these sections until we reach underseal that is still solidily attached to the car, taking this back to bare metal where ever possible. Then we treat the area withan etch primer to help the underseal to stick properly to the metal.

Here's an example of this type of work (taken from a MK3).

After completing this process, we clean the underside of the car again and start to apply the underseal product. We use a wax type product.

Here's a gallery of the car before the work is undertaken:

Here's some pictures of the same car after the work has been completed.

We don't treat inside the sills. If you do use a cavity filler, you stop the drains working and just allow the condensation build up and rust the car from inside. The drains and designed to remove this condensation. All when it comes to the time there is a need to repair the internals of the sills, this product would need to be removed as it is a fire risk when welding!

Typically, this work takes between five and seven hours to complete and requires the underside to dry. We can dry a vehicle if it arrives damp or wet.

We can refurbish your wishbones and subframes but it is expensive not least because of the cost of genuine Mazda bushes.
