Like the rest of the HydrO2 line it is made with hydrophobic glass fibres, and it can be used on paint, glass, plastic, wheels, calipers and wheel wells. Use it through a foam lance at 1:9 or in a bucket at 1:20, then wash with a mitt and rinse.

Expert Notes

Hydro Foam suits anyone who wants protection without a separate sealant step. The layer forms during the rinse: CarPro calls it hydroelectric bonding, where the pressure of the water speeds up how the glass-like shell bonds to the surface.

Used at each wash, it keeps the car beading between bigger details. For a longer layer on top, CarPro HydrO2 spray sealant is the next step up.

Once bonded, CarPro says the glossy coat resists nearly all acids, alkaline solutions and solvents and offers significant UV protection. Keep it out of the sun: on hot panels it can streak.

Perfect For / Suitable Surfaces

  • Paintwork
  • Glass
  • Exterior plastics
  • Wheels
  • Brake calipers
  • Wheel wells

Caution: Work in the shade on cool panels. In sun or heat it may streak.

How To Use

Foam lance

  1. Work in the shade and rinse the vehicle thoroughly.
  2. Dilute 1:9 and close the foam gun valve completely.
  3. Apply Hydro Foam all over the vehicle.
  4. Wash straight away with a mitt and rinse thoroughly.

Bucket wash

  1. Work in the shade and rinse the vehicle thoroughly.
  2. Dilute 1:20 in a bucket.
  3. Wash the vehicle section by section with a wash mitt.
  4. Rinse each section straight after washing it.
  5. Dry the remaining water with a drying towel or a blower.

Top Tip: Do not use Hydro Foam in the sun or on hot panels, as it may streak. If it does, apply some to a wet microfibre towel and wipe.

HQ Suggests Tips & Insights

  1. Rinse the car well before you start so loose grit comes off first.
  2. Close the foam gun valve fully when you use the 1:9 mix.
  3. Rinse each section soon after washing it.
  4. Dry by towel or blower for the clearest finish.
  5. Never wash in direct sun or on hot panels.

The Brand

CarPro

CarPro is the car care brand behind CQUARTZ, one of the ceramic coatings that brought nano-protection from professional detailing studios to everyday enthusiasts. Founded in 2009 by car enthusiasts, CarPro develops and makes its products in its own laboratory and factory, and it has grown from a single coating into a complete system for paint, glass, wheels, tyres, plastics, leather and fabric.

The range is built to work together. The shampoos and snow foams clean a coated car without leaving gloss enhancers or silicones that would mask the coating, and the compounds and polishes are body shop safe, with no fillers to hide defects. The same products suit a first-time coating at home and the upkeep of a professional CQUARTZ installation.

At The Drivers HQ we stock the CarPro products our customers use most, from Reset shampoo and IronX fallout remover to the CQ UK 3.0 coating, with much of the range on the shelf at our Ilkeston shop.

The CarPro range: prepare, protect, maintain

CarPro organises its products around the order you work on a car, which makes it easy to build a kit that suits your car and the time you have.

Prepare. Clean and decontaminate first. Lift is a concentrated pre-wash snow foam, IronX dissolves iron fallout with an acid-free, pH-balanced formula and turns purple-red as it works, and TRIX removes iron and tar in one go. For paint correction, ClearCut takes out scratches as deep as P1000, Fixer cuts and finishes in a single step, and Reflect refines the finish before a coating. Eraser then removes polishing oils so the coating can bond.

Protect. CQ UK 3.0 is CarPro's consumer ceramic coating: 70% SiO2, applied from 3 to 40°C and rated for 18 to 24 months. There are dedicated coatings for film and plastic trim (CQUARTZ Skin), glass (GForce, built on CarPro's DQUARTZ nano-diamond technology) and leather (CQuartz Leather 2.0), plus quicker options such as HydrO2, a spray-on, rinse-off silica sealant rated for up to 6 months.

Maintain. Reset is the pH-neutral shampoo made for coated cars and dilutes 1:500. Hydro Foam washes and leaves a silica layer in one step, ECH2O is a waterless wash and quick detailer, and MFX restores the absorbency of your microfibre towels.

Shop CarPro by type: ceramic coatings, snow foam, iron and fallout removers, compounds and polishes, paint sealants and glass coatings.

Where to start with CarPro

New to CarPro? Start with the products that make the biggest difference to a normal wash: Reset, Lift and a pair of Dilute bottles, which have printed ratios from 1:1 to 1:30 so every concentrate is mixed correctly. WheelX is the CarPro product our customers buy most often: a ready-to-use wheel cleaner that is safe on coated, chrome and powder-coated wheels.

Ready to protect your paint? Work in this order:

  • Wash with Lift and Reset, then remove iron fallout with IronX.
  • Polish if the paint needs it, from ClearCut for deeper marks to Reflect for a final finish.
  • Wipe each panel with Eraser and apply CQ UK 3.0 one panel at a time.
  • Keep the coating at its best with Reset and a top-up of HydrO2 or Hydro Foam every few months.

For tyres and trim, DarkSide and Perl are the favourites: Perl dilutes up to 5:1, from a rich finish on tyres to a satin look on plastics, and ReTyre cleans tyres and rubber before you dress them.
