The Ultimate Foam Cannon + Snow Foam Combo

This kit combines two standouts in car care: the Rockcar Stealth Foam Cannon – Blackout Edition and Autostolz Snow Foam. Together, they deliver professional-grade foam, unmatched lubrication, and longer dwell times for a safer, more effective wash.

Rockcar Stealth Foam Cannon – Blackout Edition
Engineered for serious performance, the Rockcar Stealth sets a new standard for foam cannons:

• Unmatched Foam Output: A precision stainless steel mesh foamer and correctly sized orifice produce thicker, denser foam than any other cannon we’ve tested.

• Fully Serviceable & Customisable: Swap orifice sizes, replace parts, or upgrade hoses and filters — everything is designed to be maintained and modified.

• Durable Build: Solid brass body with a thick black epoxy coating for chemical and corrosion resistance, stainless steel fittings, and a reinforced wide-mouth bottle with accurate metric markings.

• Precision Controls: Fine-tune soap mix, foam spread, and spray angle for perfect coverage — even keep the bottle upright while spraying at different angles.

• Smart Bottle Design: Large, clear bottle with a long, filtered intake hose prevents clogging and ensures consistent foam, even when the liquid’s running low.

Autostolz Snow Foam – Maximum Lubrication & Dwell Time
This is the highest-foaming snow foam we’ve ever tested — and we’ve tested plenty.

• Ultra-Dense Foam: Creates a thick blanket that clings for up to 5 minutes, softening and loosening dirt before you touch the paint.

• pH Neutral & Safe: Won’t strip waxes, sealants, or ceramic coatings, and is safe on matte and satin finishes.

• Pure Pre-Wash Performance: No waxes or SiO₂ — just maximum foam and lubrication to reduce the risk of swirls.

• Real-World Tested: In Christchurch trials, it matched the cleaning power of strong alkaline pre-washes without the paint risk, leaving well-maintained cars so clean that a mitt wash wasn’t always needed.

Why This Combo Works
The Rockcar Stealth gets the absolute best from any snow foam — and Autostolz Snow Foam is formulated to take full advantage. The result is a safer wash, better cleaning, and that satisfying thick foam coverage every time.
