WAR Underbody Rustproofing Superwax


WAR is not only superb for underbody use when rustproofing a chassis, undersealing, sound deadening resonance suppression, Thermal insulation and preventing further Rust forming, but also as a cavity wax for protecting hard to reach areas.

WAR. is a tough, touch dry, impact and abrasive resistant underbody coating. WAR has a number of unique features that ensure it will outlast a wet wax, and most coatings, all the while being incredibly simple and convenient to apply and use.



  • Tough Durable Superwax with superb coverage
  • Wets out correctly, expelling moisture, and air from existing corrosion halting degradation.
  • Direct to rust treatment (can be further upgraded using Rust Encapsulator primer.
  • Self heals / Resists damage
  • Deflects road dirt, salts and debris
  • Highly resistant to pressure washing, road salt spray, and harsh environments.
  • Resistant to many chemicals in reasonable concentrations
  • Bonds to almost any surface with minimal preparation including Galvanised steel, aluminium, stainless, plastics, rubber
  • Remains flexible even at lower temperatures
  • Deeply penetrates rust/ Superb as a cavity wax
  • Infused with Vapour Phase Inhibition, expelling local air and creating an air barrier around the coating (especially effective in cavities)
  • Highly resistant to failure from contamination


  • Vehicle chassis / Frame/ Underbody
  • Flexible components including leaf and coil springs
  • Penetrating and sealing spot welded sections such as inner arch struts that harbor moisture between spot welds
  • Door cavities, internal panel areas, bulkhead cavities, and unfinished areas behind binnacles
  • Helps prevent galvanic corrosion
  • Body mounts and areas that you are not able to fully disassemble


  • BLACK - As it says. A standard black coloured WAR
  • TINTABLE With Tint. WAR, but provided with an additional pot of colour of your choice (almost any colour you want!). 
  • TINTABLE WITHOUT Tin (as above, but without any colour in it. We do this so that you can order your colour separately
  • PLATINUM- The highest grade of War (Previously Stage 3)- Infused with our compound to assist with :-
  1. Sound Deadening -WAR Now limits sound transfer
  2. Resonance Suppression -WAR Now actively combats resonance produced from panels
  3. Thermal Insulative properties -WAR now significantly limits heat loss, and reduces energy required to keep a cab cool.
  4. Ceramic -WAR is now more resistant to abrasion, gouging and has increased longevity due to increased porosity resistance

By selecting the Platinum option you are purchasing the highest grade of WAR we can produce. For ultimate sound and thermal insulation we recommend applying WAR over Cosyfoam.


Product Types
1000ml Paint Tin
Normal paint tin for brush / roller / thinning and spraying

1000ML Schutz Undercoating Tin
Stubby Schutz Tin. These tins work with our FX10 Spraygun & FX11 Spraygun. The gun screws directly on. To use a normal Schutz gun with a stubby schutz tin, you need to trim the pickup tube 75mm shorter.

5000ml Paint Tin
Normal paint tin for brush / roller / thinning and spraying

400ML Aerosol (traditional)
Traditional aerosol.

400ML Buzzweld Powercan
The Aerosol powercan uses NO THINNER. as a result the can outputs the same amount of paint as a spraygun. This means less coats, a much higher film build and time saved. HOWEVER- the cans empty themselves very quickly. Protection VS coverage. When using a powercan you need to spray from further away. This can can also be used as a textured bedliner spray (comes with two nozzles).

Superb SuperWax
06 May 2024  | 

Comes in a handy spray can for smaller applications, its easy to apply and dries well. Still to see how it handles the abuse that the roads can throw at it but I expect good results.

Fantastic product 5*****

What a great product matched the closest RAL Colour to car colour and hoped for the best as didnít have a RAL chart at home!! Couldnít have asked for a better finish or colour match. It went on without and hassle and dried to a great Finish! Wish you could add pictures Iím that chuffed I spend more time looking under the car now! Very nervy first time attempting anything like this but spoke to the people at buzzweld very knowledgeable and helped me decide the best course of action and the quantity and measurements they gave were spot on!

Like the rust encapsulation product I will use this again

WAR UNDERBODY on F100 truck bed
31 May 2023  | 

Was recommended to use this product, mixed with tint at 100ml to 1 litre. Seemed to be a fair match for colour once applied with 4" roller, fairly thick product with great coverage. Don't over roll as it tacks off quite quick, when I applied it was18 degrees.

I was new to the Buzzweld products. Got some great advice from the Buzzweld team on which to use for my project. Gave it two coats of RE followed by two with WAR. I used the 1 ltr tins and both brush on great and cover really well.

13 January 2023  | 

Brilliant product - I have recently treat my new galvanised Landrover chassis to two coats of GIO followed by 2 of War and was extremely impressed with the quality and finish- bought 2 more aerosols of War to coat the wheel arches and it was so easy to do. I totally recommend it.
