Now the BMW E30 restomod build has an MOT and I'm actually driving the car, I continue to be paranoid about protecting the underbody.

Those of you who have followed along with the restoration process of this retro classic car will appreciate how much time and effort went into the underside of it. Having stripped the car completely, and welded up all the rust holes and treated the underside I applied Dinitrol 447 underseal along with their ML cavity wax.

I've been very happy with this coating and I am confident it will last a very long time and protect the car from rust. However, I never intend to restore this car again and want to keep the underside free of rust and in the sparkling condition it is now, and to do that I intend to add an annual application of a lanolin based protection.

This yearly coating I will be using as more of a sacrificial layer just to protect the car. But I am also confident it will help prevent road grime and must from sticking to the underbody while its being enjoyed.

This use-case is a viable one for a lanolin chassis protection, but this Buzzweld Chassis Guard product is capable of far more than that. It's a fully natural product which is specially formulated for automotive use, although can also be used to restore plastics and protect wood. Buzzweld is a very well regarded brand in the automotive restoration space so they have come up with their own blend.

Chassis Guard can be applied directly to rusty areas to make them more water-repellent and to seal them from air and moisture, preventing the progression of rust or corrosion.

It has also been known as a way to maintain patina on a car without allowing it to progress further. If applied to rust it makes the bright orange and dusty appearance become a darker brown shiny look which is far nicer on the eye.

If you are planning to apply this coating to your own classic car, it's strongly advised that you clean away any dirt or grime from the underside beforehand, to give the lanolin chance to properly stick and get into all of the areas it needs to protect, without dirt being in the way.

As my BMWs underside has recently been restored, and I've only driven the car 200 dry miles since, this simply meant brushing the dust from it, and it was ready to go.

Before starting out I got the car lifted onto the wheel cribs and masked the exhaust pipe, you don't want to apply this type of product to something which gets as hot as an exhaust pipe, its not necessarily a fire risk, but I'd expect it to burn off and smell unpleasant, possibly leaving staining too.

Further to that I also masked my disc brakes to prevent them getting a coating of lanolin too.

I got fully masked up along with donning a painting suit. The Chassis Guard smells a bit like a mild fish oil, not the most pleasant. I doubt it could really do you any harm as lanolin is actually something commonly used in skin treatments, but when working with any chemicals it always pays to be safe and protected, especially the eyes and lungs.

I mixed my Chassis Guard with 10% White Spirit as recommended by the manufacturer when using a hand spray bottle. It's quite a thin oil so goes through the sprayer very easily without causing any annoying blockages.

I removed the wheels from the car and gave the wheelwells a generous coating of lanolin oil and them moved onto the underbody where I coated everything, paying special attention to areas I know are common for rust on the E30.

The beauty of this product is it can be applied to almost anything without issue, including components I was not prepared to coat with Dinitrol previously, such as the fual tank, rear subframe, rear arms and some other suspension components.

After using around 3/4 of a litre and applying a very heavy coat, I was done and the excess lanolin simply dripped onto the floor. My advice is to clean up any excess before it dries using a rag with white spirit on, as after the coating had dried, it becomes very stubborn leaving a shiny clear coating.
