303 Products Touchless SiO2 Sealant Refill 1 Gallon — Spray & Rinse Hydrophobic Protection for Paint, Glass, Wheels

303 Touchless SiO2 Sealant Refill (1 gallon) is a spray-and-rinse SiO2-based sealant that delivers long-lasting water beading and surface protection without scrubbing or polishing.

If you want the hydrophobic performance of a ceramic boost but lack time for a full wax or machine-applied coating, this one-gallon refill from 303 Products offers a fast, touch-free solution. The SiO2 chemistry bonds to exterior surfaces to encourage water to sheet and bead, making rinsing easier and helping contaminants roll off. It’s formulated for multiple substrates including automotive clear coat, glass, gelcoat, fiberglass, plastics and wheels, which makes it a versatile option for owners who want protection across an entire vehicle or multiple vehicles.

How does a touchless SiO2 sealant work and what can I expect?

The product sprays onto a wet vehicle surface and is rinsed off, leaving behind a silica-rich layer that repels water. Expect rapid application: most cars can be treated in minutes rather than hours required for traditional waxes. Results include improved water beading and easier drying after washes.

• Spray on any wet surface, wait briefly, then rinse with a hose or pressure washer.
• Forms an invisible, hydrophobic film that encourages water to sheet and bead.
• Compatible with paint, glass, plastic trim, gelcoat and wheels.
• One gallon size is suited for frequent use or fleet maintenance.

How long does protection last compared to standard waxes?

While longevity varies with climate, wash frequency and driving conditions, SiO2 sealants typically outlast conventional carnauba waxes. This formula is designed to resist breakdown and maintain hydrophobic performance through repeated washes, extending the interval between full detail sessions.

• Improved durability versus many traditional waxes under normal conditions.
• Maintains water beading over multiple washes when applied correctly.
• Ideal for extending the time between polishing or re-waxing cycles.
• Safe for use on ceramic-coated vehicles as a maintenance boost.

Can I use this on glass, wheels and nonpaint surfaces safely?

Yes—this 303 formula was developed to be substrate-friendly and works across a range of exterior surfaces. It won’t require separate products for windshields, plastic trim or gelcoat, simplifying the maintenance routine for boats, cars and recreational vehicles.

• Clear coat and paint: preserves gloss while repelling water.
• Glass and windshields: improves runoff for clearer vision after rinsing.
• Wheels and plastics: adds hydrophobic behavior without harming finishes.
• Gelcoat and fiberglass: compatible for marine applications.

What is the easiest way to apply the one-gallon refill for best results?

For fast coverage, dilute according to label instructions if recommended, attach a pump sprayer or refill a consumer spray bottle, and work panel by panel on a wet vehicle. Rinse each area after application to reveal the protective layer, and allow surfaces to air dry or use a microfiber towel for speed.

• Use a pressure washer or hose to wet the vehicle before spraying.
• Spray evenly, wait a brief dwell time, then rinse thoroughly.
• For large jobs, pour into a pump sprayer to speed application.
• Store sealed; product shelf-stable for up to two years from the bottle date.

Who is this for: The 303 Touchless SiO2 Sealant Refill in one gallon is aimed at car owners, detailers and fleet managers who need a fast, effective hydrophobic treatment that covers multiple surfaces. It’s especially useful for people who prefer minimal contact during maintenance, have limited time for detailing, or want a maintenance product to prolong the effects of existing waxes or ceramic coatings. If you need a single, versatile product to boost water beading and simplify rinsing across paint, glass, plastics and gelcoat, this SiO2 touchless sealant is built for that purpose.
