Chassis Paint Black Satin CIO Chassis In One

Targeted at our customers who want a simple, medium term (up to 10 years estimated) solution for protection of Chassis and Underbody compared to our extreme 4 coat dual product system.

Buzzweld CIO is a high adhesion Corrosion stabilising primer and top coat in one.

Buzzweld CIO system requires just two coats to protect your chassis (brush/ schutz applied, more for other application methods)


  1. Contains self-leafing glass flake for extreme abrasion resistance compared to standard coatings.
  2. Double acting on rust! The only coating in the world we are aware of that is both Rust Stabilising, and high in zinc content.
  3. Contains a corrosion inhibiting pigment for class leading, rust prevention by stabilising corrosion to a lower reacting form
  4. Over coating times are as little as 30 minutes, meaning no breaks required between coats in most situations.Designed from the ground up for hand prepared steel.
  5. Primer, and top coat in one. You save significant amounts of time and money with this system that will still outlast most competitors (not our extreme system).
  6. Low Satin / matt finish for oem look.
  7. Suitable for over-painting firmly adherent existing rust.

Chemically modifies rust over time.



  • PLATINUM UPGRADE- The highest grade of CIO- Infused with our compound to assist with :-
  1. Sound Deadening -CIO Now limits sound transfer
  2. Resonance Suppression -CIO Now actively combats resonance produced from panels
  3. Thermal Insulative properties -CIO now significantly limits heat loss, and reduces energy required to keep a cab cool.
  4. Ceramic -CIO is now more resistant to abrasion, gouging and has increased longevity due to increased porosity resistance
  5. Increased porosity resistance- Longer life

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

Easy to apply and looks hard wearing, also well worth the money.

Far better to work with than other products
27 May 2024  | 

I've used a number of other similar products over the years, but since someone told me about CIO, I've got to say, this is, hands down, the best. Application was quick and easy, and less messy than other alternatives. Highly recomended.

Quick drying with good coverage
22 April 2024  | 

Paint was easy to apply and quick drying allowing for additional coats to be applied whilst tacky to finish the project.
Used for the inside of chrome bumpers to protect from rusting further

Motorhome tidyup

Rear chassis rails under the garage area looked a bit tatty with surface rust. No structural issues. Removed the surface rust and repainted with a brush using CIO. Excellent result visually and easy to use. Dries very quickly so its easy to complete the job in one stretch.

Perfect chassis paint
16 December 2023  | 

Having tried the paint on its own and with rust encapsulating primer I continue to be impressed by its performance on the chassis of my 90 and also as finish for the external cage. It has outperormed a well known altewrnative using epoxy primer systems in inhibiting rust reappearance. An excvellent product!

Excellent paint.
26 August 2023  | 

I originally bought two tins of brush on paint for my 1988 Land Rover chassis, it was easy to apply and dried to a very nice finish. I then bought some spray cans to get into the numerous areas a brush couldnít easily reach, especially the rear cross member.
Overall Iím very happy with the paint and especially the nice smooth finish.
I will definitely use Buzzweld coatings again.
