Automotive underbody coatings complete car protection
So much attention is given to the coating and paintwork of the visible aspects of a vehicle that those unseen places get overlooked. The underbody is one such place. Underbody coatings protect a vehicle from everything the road can throw at it and more: they provide a layer of protection between a vehicle’s more vulnerable underside and damaging forces such as corrosion and moisture ingress. In this article we will outline the benefits and types of automotive underbody coatings, and where you can find products and applicators in the UAE.
Choose from 3 types of automotive underbody coatings
Automotive underbody coatings can be factory-applied or aftermarket. Most commonly these coatings are bitumen, resin, and wax based.
- Bitumen: These underbody coatings provide hard-wearing protection against stone chip damage and corrosion. They also have sound-deadening properties. Suitable across many substrates, but cannot be painted over. Can be applied by brush or spray, high build, and good for very tough conditions such as off-road.
- Resin: Polyurethanes and rubber-based coating are popular because their elastomeric properties provide long-term stone chip damage and corrosion protection as well as sound deadening effects. These also have the benefit of being suitable for a wide range of substrates and they can be painted over. Can be spray-applied, high build, and particularly good for there where salt exposure is possible.
- Wax: An excellent anti rust coating suitable for all substrates. The wax is applied soft and cures hard, either by brush or spray, and can be layered thickly. It cannot be top coated.
Automotive underbody coating suppliers and applicators in the Emirates
Underbody coatings for consumers are strictly aftermarket and dealer- or shop-applied. Dealers and automotive shops across the Emirates provide these services. The coatings themselves are provided by companies such as AkzoNobel, DINITROL, Henkel, and Sika. The cost of an anti rust underbody treatment varies across vehicle size, as well as how much preparatory surface treatment needs to be done, and which coating type is to be applied.

5 reasons to go for an underbody coating
If you have ever travelled in an old car down a gravel road you have heard the thunderous sound of hundreds of tiny pieces of rock being hurled at the underside of a vehicle. Not only is it deafening, it is also damaging. The functions of an underbody coating include the following.
- Preventing rock chip damage – An underbody coating provides a durable elastic over the underbody and wheel arches which protects the substrate from stones, gravel, salt, and other debris which is thrown up by the road.
- Minimizing sound – The noise of debris hitting a vehicle, or vibrations from the road can be dampened by the application of an underbody coating. They prevent vibrations and because they are elastic they make far less noise when struck than the metal underneath.
- Being easy to maintain – Giving the undercarriage of a vehicle a uniform appearance means cleaning it down is simpler and so is identifying possible problems.
- Protecting from corrosion – The automotive coating process consists of at least five layers of protective and decorative paint. However, the underbody only receives the first two layers – the layers that provide the corrosion protection. But if that is the case why would another layer of coating be needed to protect from corrosion? The initial two layers provide corrosion protection, but are not very durable. Stone chip damage may expose the metal itself, leading inevitably to corrosion.
- Preventing water ingress – By covering cracks in the paintwork or joints in the undercarriage of a vehicle, moisture or water from humid or wet environments is prevented from creeping into the underbody and causing corrosion.
