About CARPRO HydrO2 Concentrate

HydrO2 is a touchless spray sealant in a concentrate that allows for the protection on all surfaces using a pressure washer or hose.

CARPRO HydrO2 Concentrate is a cutting-edge, silica-based spray coating & sealant designed to protect paint, glass, wheels, trim and more, without even touching the surface. It sprays on and rinses off, bonding instantly to form a durable, UV-resistant and glossy barrier that repels water, dirt and fallout.

Formulated as a concentrate, it delivers outstanding cost-effectiveness. Just 40ml of product, when diluted, is enough to fully coat a standard sedan, including paint, glass, plastics and wheels. It’s one of the most efficient car sealant options available for high-volume or professional use. This is the ideal solution for protecting areas that are usually skipped due to access or time constraints. Undercarriages, wheel wells, door jambs and trim seams can now be sealed in seconds. With no wiping or curing required, it also eliminates risk of marring soft paint and dramatically increases workflow speed.

HydrO2 doesn’t just protect, it improves the look of the vehicle too. The finish becomes slicker, glossier and beads water like a freshly waxed surface. Whether you're using it as a standalone spray coating or as a maintenance topper, HydrO2 offers up to 3 months of protection in a product that takes less than 15 minutes to apply.

Key Features
  • Touchless Spray Coating: No wiping required, apply and rinse for instant protection.
  • Incredible Efficiency: Only 40ml needed for a full sedan when diluted.
  • Extreme Water Repellency: High hydrophobicity for easy maintenance.
  • UV and Chemical Resistant: Durable barrier against environmental fallout.
  • Gloss-Enhancing Finish: Adds slickness and clarity to all surfaces.
  • Ideal for Hard-to-Reach Areas: Safely coat undercarriages, jambs and trim edges.
Directions & Dilutions
  1. Do not apply in direct sunlight or to a hot surface.
  2. Thoroughly wash the vehicle. Use CARPRO IronX Snow Soap for best prep.
  3. Rinse all soap residue from the surface with clean water.
  4. Dilute HydrO2 at a ratio of 1:6 to 1:10 with water in a spray bottle.
  5. Lightly mist the diluted product onto one panel at a time.
  6. Rinse off immediately with strong water pressure, do not let the product dwell for more than 1 minute.
  7. Use a flood rinse (no nozzle) to push remaining water off the surface.
  8. Dry remaining moisture with a microfiber towel or air blower.

Reviews Summary
Customers say this car sealant spray provides excellent water beading and shine while being remarkably simple to apply. Users report just spraying the diluted product on clean vehicles and rinsing off for quick results. Many mention the outstanding water-repelling properties and glossy finish that significantly reduces washing and drying time. Customers find it works particularly well on wheels and headlights, making difficult areas easier to maintain. Most praise the product's effectiveness in keeping cars cleaner longer. However, some caution about careful application on dark or hot paint to avoid streaking, and one notes it can leave spots on glass if allowed to dry.

    CARPRO HydrO2 Concentrate

    This review is long overdue. I’ve been using this for quite a while now, and the concentrated version definitely lasts longer on the car than the lite one. Tried a few different brands of similar products, but always end up coming back to this.

    It lasts about a month on a daily driver that lives outside 24/7. On the car that stays in the garage and only gets driven mostly on weekend it lasts quite a bit longer. Definitely the easiest and most effortless way to keep a car protected.

    Overdue, but always welcome. Glad to hear that you have had such a quality experience with the HydrO2. Stoked that you find it so easy to use and that you're finding the protection lasts!
