Rockcar Stealth Foam Cannon – Blackout Edition

Engineered for performance. Built to last.

We've tested the Rockcar Stealth against many of the leading foam cannons on the market and haven't found one that produces better foam.

What really impressed us, however, was the engineering. We took one apart to see how it was made and were impressed by the quality of the internal components, especially the details you don't normally see.

Unlike many foam cannons designed primarily around appearance and price, the Stealth is engineered for foam production, durability and serviceability.

• Exceptional Foam Production: A precision stainless steel mesh foamer and carefully selected orifice produce thick, dense foam. The supplied 1.1mm orifice suits many domestic water blasters, with alternative sizes available for different pressure and flow requirements.

• Fully Serviceable & Customisable: Replacement bottles, stainless steel mesh filters, orifices, hoses and other components are available. Maintain, repair or modify your foam cannon rather than replacing the entire unit.

• Durable Construction: Solid brass housing with a thick black epoxy coating for additional chemical and corrosion resistance, plus quality stainless steel fittings.

• Precision Controls: Independently adjust the soap concentration, foam spread and spray angle. You can even rotate the spray pattern while keeping the bottle upright.

• Thoughtful Bottle Design: Large, clear bottle with accurate metric markings and a wide opening for easy filling. The long, flexible intake hose includes a filter to help reduce debris entering the foamer mesh.

The Stealth uses a standard ¼-inch quick-connect fitting and can be connected to a wide range of pressure washers using our adapters.

It's a premium foam cannon that's designed to perform exceptionally well and remain serviceable for years.

Autostolz Snow Foam – Powerful Cleaning, Maximum Foam & Lubrication

Advanced surfactant chemistry. More cleaning time. Exceptional lubrication.

This is the highest-foaming snow foam we've ever tested — and we've tested plenty.

But impressive foam is only part of what makes Autostolz Snow Foam so effective.

Its advanced surfactant chemistry is designed to loosen and lift dirt and road grime, while the exceptionally dense, stable foam clings to vehicle surfaces for longer.

Dwell time makes a real difference to cleaning performance. By keeping the cleaning solution in contact with the surface for longer, the surfactants have more time to work on dirt and contamination before rinsing.

This allows Autostolz Snow Foam to deliver excellent cleaning performance without relying on strongly alkaline or acidic formulations, which can be harsher on some vehicle surfaces and protective finishes.

The formula also provides exceptional lubrication, helping reduce friction during contact washing and lowering the risk of fine scratches and swirl marks.

Why it works so well:

• Advanced Cleaning Chemistry: A carefully formulated surfactant system delivers excellent cleaning performance without relying on strongly alkaline or acidic ingredients.

• Extended Dwell Time: Thick, stable foam clings to vehicle surfaces, giving the cleaning agents more time to loosen and lift dirt before rinsing.

• Exceptional Lubrication: Helps reduce friction between the wash mitt and paintwork, reducing the risk of wash-induced scratches and swirl marks.

• pH Neutral: Ideal for regular maintenance washing and designed to be compatible with ceramic coatings, waxes and sealants when used as directed.

• Suitable for Different Finishes: Safe for gloss, matte and satin finishes when used as directed.

• Pure Cleaning Performance: No added waxes or SiO₂ protection. Formulated for maximum foam, effective cleaning and lubrication.

Why Use Snow Foam Before Washing?

A good pre-wash helps loosen and remove dirt before you touch the paint.

The more dirt you can safely remove during the pre-wash and rinse stages, the less contamination remains to be dragged across the surface during contact washing.

Autostolz Snow Foam combines effective cleaning chemistry with extended dwell time to help maximise this pre-wash cleaning, while its excellent lubrication provides an additional benefit during contact washing.

It's not just about making more foam. It's about giving the chemistry more time to work.

Why This Combination Works So Well

A great foam cannon does more than produce impressive foam. It helps your snow foam work more effectively.

The Rockcar Stealth uses a precision stainless steel mesh foamer and carefully engineered water flow to produce exceptionally thick, stable foam.

Autostolz Snow Foam is formulated to take full advantage of this, creating a dense layer of cleaning solution that clings to the vehicle rather than running off quickly.

This extended dwell time gives the surfactants more opportunity to loosen and lift dirt before rinsing. The soap's excellent lubrication also helps reduce friction during contact washing.

Together, they deliver three important benefits: effective cleaning, extended dwell time and exceptional lubrication.

We've tested a lot of foam cannons and snow foams, and this is a combination we're particularly impressed with. It's why we've brought them together in this kit.

Choose the Right Adapter for Your Water Blaster

We've made finding the right fitting easier.

Different pressure washer and water blaster manufacturers use different connections, and some brands have changed their fittings between models.

We've spent years checking water blasters sold in New Zealand and sourcing quality adapters to suit as many models as possible.

Simply select the correct fitting from the options above. Your kit includes your selected adapter to connect the Rockcar Stealth Foam Cannon to your water blaster.

Where Does the Foam Cannon Adapter Connect?

The adapter connects to your water blaster at the first detachable connection immediately after the trigger, as shown in the diagram.

Remove the long spray lance from your trigger handle and connect the foam cannon in its place using the correct adapter.

Important:

• Not at the end of the long lance: The weight of a full foam cannon puts unnecessary strain on the lance. Some water blasters also use a different fitting at this point.

• Not at the hose connection: The foam cannon must connect after the trigger so you can control the water flow.

Check the fitting shown in the diagram, not the connection at the end of the lance or where the hose attaches.

Some fittings look very similar but have different dimensions, so check the shape and pin length if you're unsure.

If you need help identifying the correct adapter, send us a photo of the connection on your trigger handle and we'll help you find the right one.

Important: Please check your water blaster's connection before ordering. Some manufacturers use different fittings across their models, and the brand alone doesn't always identify the correct adapter.

Ryobi & Ozito – Check Your Fitting

Ryobi and Ozito have used different connections on older and newer water blasters. We offer both short and long adapter options.

Some newer models use a shorter fitting. Our solid brass short adapters fit the corresponding connections, but their compact design makes them more difficult to grip and twist in and out than the older, longer fittings.

We want you to be aware of this before ordering.

How to Use Your Foam Cannon Kit

1. Prepare: Shake the Autostolz Snow Foam bottle well.

2. Mix: Add 30–90ml of Autostolz Snow Foam to the 1-litre foam cannon bottle and top up with water.

3. Connect: Attach the Rockcar Stealth to your water blaster using the selected adapter.

4. Apply: Foam evenly onto a cool, dry vehicle in the shade.  Do not use on a hot car or in direct hot sunlight on a hot day.

5. Dwell: Allow approximately 3-5 minutes for the cleaning agents to work. Do not allow the foam to dry.

6. Rinse: Rinse thoroughly, working from the bottom upwards and then back down.

7. Contact Wash: Follow with a contact wash where necessary.

Important: Use on cool surfaces below 30°C, avoid direct sunlight and never allow the product to dry on the vehicle. Always test on an inconspicuous area first.

Compatibility: This kit is designed for pressure washers (water blasters), not standard garden hoses.  If you want one for a standard garden hose, we recommend the rockcar foam gun kit here.
