Chassis Paint -  How to choose Guide


When choosing a Rustproofing Paint to protect or refinish your Chassis its a big decision. Chassis paint is the analogy of "i need a car". There are so many factors to consider. The very last thing you decide is "what chassis paint" to purchase. Before that you need to consider this:-


  • How much will my chassis paint cost?

            Yes, we tend to go for "the minimum amount i NEED to spend", but be realistic. If you want special colours, you want it to last for "as long as possible", you want a texture, you want the advice to go with that its going to cost. Thats just the product cost. There is no point spending £200 on a superb undersealing protection kit like the 2K armour Chassis Protection kit if you do not meet the requirements of the kit, such as good preparation, a solid key, nothing too smooth, and that you are able to take your time applying it. Set aside some realistic expectations, if you only have £75 to spend on the entire underbody you want to split 30% of that budget into preparation materials BEFORE paint.

  • What preparation​ does Chassis Paint require?

            If your idea of preparation is a jet wash down and spray it on, or if you know what preparation is and know that your going to get half way through your project and start cutting corners then factor that in to your purchasing decision. You need to decide if you are going to have that chassis prepared back to bare metal, keyed, rust removed, degreased, contamination removed and ready for your coating exactly how it needs it, or if you really don't have the time and facilities to do a "proper job". If you cannot realistically do the prep for a coating, then DO NOT choose it. Choose something more preparation tolerant, or get the chassis protected for you by an application centre who will do the required preparation, and give you peace of mind without lifting a finger. IF none of those are option simply choose a product that is more preparation tolerant, and more likely to give you the desired protection and results like WAR Wheel arch refinement Underbody Protection.

  • How long do you want the rustproofing treatment to last?

           "As long as possible" is not an answer. set a target, 1 year, 3 years, 5, 20, 30, and base your choice around how long it CAN last. then do the proper preparation, and in most cases with most products both ours and others you will achieve the longevity you require. The longer a coating can last, the better the return on your investment of time and money. If you want it to for example last 10 > 20 years then go for a full chassis paint kit. You need to read up on what the coating or protection being offered is, and what kind of preparation is required.

  • What conditions is the underside of the vehicle going to be exposed to?

      Longevity on any chassis paint is affected by several contributing factors. how it was applied,  was it prepared properly,  and in what environment(s) will it be used in. Doing no prep, applying a product too thin because you didn't purchase enough, and then using it in the sea could see a coating designed to last decades protect for less than 30 minutes. ALL COATINGS ARE A COMPROMISE, and if you are not realistic about that, no matter the marketing, then you will in most cases become dissapointed. If you are using your vehicle in or around the sea an epoxy based product is usually a safe bet, however within the "epoxy" umbrella of coatings you have massive variation from low adhesion rebranded floor paint, to paint designed not to flex, etc etc. you again need to decide on what type of epoxy coating you would like to use

  • What Chassis Paint do i purchase?

      Now knowing what preparation you are able to achieve, your budget, how long you want it to last, and the conditions you are planning to use it in you are now able to select the best "compromise" coating for your individual needs.


Remember. Match your budget, to your needs, and your expectaions when selecting a coating, and you won't go far wrong.

Good morning, I am from Malta and I have a Land Rover Defender 90. I have sand blasted the chassis and put some primer. Can you please advise what product I can use for chassis protection with a smooth black semi gloss top coat? Regards

Hi just bought a 2005 sprinter lwb and i am wondering how much product i will be needing . I.E cavity wax 6 doors and chasis -rpc for inside floor - cio undeside -and war wheel arch thanks . karl

Hi Karl.
For the internal floor area i would recommend Rust Encapsulator here 5 Liters possibly a touch more

For the underbody i would go for another 5 liters of Rust Encapsulator, followed by 5 liters of CIO Chassis In One here

Wheel arch wise you can use up any spare RE and CIO and then use war as a top coat.

If you need sound deadening don't forget to take a look in the shop here.

I have a Land Rover Series 3 Chassis that was Galvanised in the 1990's it now has a couple of rust spots, as I am giving the Land Rover a full restoration what paint would you recommend for a long lasting, standard Land Rover look and to be OK with steam cleaning and dinitrol. Also would you recommend getting the chassis blasted before paint?
Cheers Kyle

Hi Karl. i would degrease and scotchbrite to remove any loose/ friable. then i would use two coats of rust encapsulator, topped with Chassis In One. i would not top coat it with dinitrol, as it will survive fine by itself, however i would recommend WAR if you wanted to top it up with a sacrificial wax.

RE is here

CIO satin black chassis paint is here

and WAR underbody wax is here

Hello, I have a LR 90 stripped to rolling chassis and plan on using your products to protect the chassis as good as possible including general underbody and fuel tank. I have a compressor to use in the garage as well. Im going to fully prep everything and I want to use something to cure and convert the rust and then a nice OE black finish. What are the products/ kit to recommend for me, thanks

Hi Chris,

I would go for a schultz Applied Chassis In One kit here. it has the gun, cavity wax, prime, and everything you need.
