Buzzweld U.P. Underbody preservation is a borosilicate glass re-enforced underbody clear lacquer with exceptional anti-corrosive properties..

UP Underbody Preservation Chassis Care Ceramic

U.P. is specifically formulated so that it can be applied to a wet surface that has had minimal preparation.  U.P. will offer short to medium term protection above that of oils, and other waxes at low preparation levels.

Benefits include

  1. Clear- U.P. does not hide existing issues. you can spot problems as they occur and maintain accordingly.
  2. LOW reactivity. U.P. is compatible with most existing paints and treatments making it ideal as a Patina Preserver, and a topup protection system.
  3. EXTREME creep from absorbtion, as well as capillary action. 
  4. U.P. flows in between spot welds, and absorbs into corrosion forcing out the residual moisture and air, suffocating the ability for corrosion to continue.
  5. COST EFFECTIVE. U.P. 1000ML Schultz tin will treat up to a larger 4x4
  6. TIME effective. a U.P. underbody treatment can be completed in as little as 2 hours.
  7. FAST CURE. U.P. can be touch dry in as little as 30 minutes.
  8. High temperature tolerance. Survives on the exhaust system up to but not including the downpipe.
  9. Forces out moisture from wiring looms, and electrical connectors.
  10. Presents an easy to clean, hydrophobic surface.
  11. Vehicle underbody stays dryer for longer, and holds less water in adverse conditions.
  12. does not wash off or evaporate
  13. TOUGH- Difficult to remove even with a 155C steam cleaner
  14. Dries properley, does not wash away, or attract dirt/ debris
  15. Makes maintenance work ALOT easier- cleaner, drier, less rust.
  16. EASY to weld, or prepare an area that has been treated.

We estimate the lifespan of U.P. conservatively to be between 12 and 36 months to first maintenance. This is based on the level of prep you do, and more importantly the existing condition.

Minimum prep requirements for U.P. is to wash down the vehicle underbody, and apply. You can apply U.P. whilst the vehicle is still wet.

Recommendations to improve U.P. longevity.

  1. Clean. the cleaner the underbody the better.
  2. wet. we recommend you use an air blow gun, or take the vehicle for a short drive prior to application where possible to remove excessive amounts of trapped water.
  3. steam cleaner. very effective at removing existng loose paint, and contamination. the more U.P. that is in contact with the vehicle, and not over existing oils, dirt, flakey paint etc, the better it will protect your vehicle.
  4. On poorly sealed vehicles we recommend you air the vehicle interior to remove solvents during the curing process. Modern vehicles will not typically require this.

Please NOTE-

  • Applying to a wet surface can lead to streaking in the finish, and water bubble "drips" at the bottom. only apply to a wet vehicle if the finish is unimportant to you. A second coat may be necessary if excessive water was left on the chassis prior to coating. If water bubbles occur, using a gloved hand wipe over them, and spray those areas back in as part of your second coat.
  • Colours are not available in the hand sprayers as yet, as it is a thinner version, and the colour can drop. We hope to release the coloured hand sprayers soon.

We recommend the FX11 Schultz gun for U.P. as it atomises better, and has much better access than a standard schultz gun. Also works with PCL, and IM gun. IM Gun offers the most control and access.

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 loaded with DTM RAL9005.

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).
As with any coating we recommend goggles, gloves, and a decent mask such as an A1P2

Does exactly what it should, easy to apply, but a bit smelly!
09 January 2024  | 

This was easy to spray on with a shutz gun. In fact the hardest part was jacking up the car. One can was enough to do my BMW 3-series... just. I did not mask anything, and just sprayed over everything avoiding exhaust and brakes as much as I could. Nevertheless exhasut did get overspray. After driving the smell of it burning off is a bit wierd. That smell lingered for days. It's been 1000 miles since I applied, and seems to have held well through heavy rainfall, but let's see what happens when it snows, and we have salt. I will check the underside before next winter and if its held up well, I will definately buy again and re-apply.

Fantastic product.

I found the coverage and quality of this product to be excellent. It was easy to cover the area of my vehicle.
The hand pump applicator needs to be looked at and improved. I know that Buzzweld is currently working on this.
In an ideal world using an air gun spray and a compressor would make applying this product easier.
Other than that I would 100% recommend Zero Prep.
Customer support was great.

Much better than expected

Bought this as a test, and I was a little sceptical. Once I applied it and saw the results, I was amazed. It left a solid coat over the areas sprayed and sealed the areas. Easy to apply and seems to do the job.

Good product - but!
12 February 2023  | 

Iíve used Buzzweld products before but this is the first time using Zero prep, itís exactly what I was looking for and is ideal for the underside and suspension of my old Jag, itís easy to apply and dries fairly quickly to a tack free gloss finish (Itís much better than Lanoguard which dries matt and stays tacky so attracts dirt)
The downside is the applicator, it needs a much finer spray pattern, so much so Iíve resorted to brushing it out after spraying to get a decent even finish, that apart itís another good product from Buzzweld!
(Iíll stick to WAR under my 4x4 though!)

Zero prep
20 November 2022  | 

My first look at the bottles was they don't look like it will cover much how wrong was I 4 bottles covered my whole freelander 2 wheel arches as well and still had a little left over and I was not skimping on the coverage
The Finnish was great and not even the mud from off reading stuck to it water just runs off now I'm so happy with the zero prep and would recommend anyone to use this product
I would have given it more than 5 stars

So easy to use in a hand spray bottle, goes off quickly even in cold weather to form hard waxy coating. Time will tell how good a job it does. but being clear it'll show up any problems.

Good Results

The aerosol gave good coverage and the final appearance on the chassis was very good. I would by again

The Bizz!
20 May 2022  | 

Used this stuff in anger on a 22year old Subaru. Blast cleaned everything first then laid it on with gun supplied and brush. Fumes are really serious even from the open tin let alone vapor from spray. You NEED a good quality respirator and overalls. Stuff needs time to cure before you run the engine or any demisters as the fumes will contaminate EVERYTHING!
IT WORKS! I've tried other stuff over the decades, this is the ONLY coating that actually withstands punishment from a tough environment. The fact that you can see through it means it can't fool you into a false sense of security - like Waxoil does!
Stone chips in the wheel arches will knock it off though so will be re-coating and bed liner top coating the arches before Autumn.
Been brushing Buzz-UP onto all metal items since - bench vice, trailer frame & hitch, granddad's bike and next doors cats and dogs etc.

Easy to apply, rather sticky though, so wear some overalls. You can get it everywhere, and seems to be holding up well. Definetly stays drier and cleaner than usual. Plan is to top this up once a year as it takes me about an hour all in including washing it down to do the underside (wash, then spray it on).
