303 Products Spray & Rinse Ceramic Sealant – Quick Ceramic

303 Products Spray & Rinse Ceramic Sealant is a water-activated SiO2 spray-on ceramic coating that delivers glossy hydrophobic protection for up to six months when applied to clean, wet exterior surfaces.

This quick ceramic coat is designed to be used right after washing — spray on a wet panel, rinse, and towel-dry — giving paint, glass, wheels, and trim a slick, water-repelling finish without disturbing existing clear coats. The formula uses silica (SiO2) to form a durable, beading barrier that reduces water spotting, dust buildup, and the cling of road grime, while adding a visible shine to your vehicle's exterior. The product arrives in a convenient 24 oz spray bottle and is made by 303 Products, a brand with over four decades of vehicle-care experience.

How does this spray create water repellency on my car?

The Spray & Rinse Ceramic Sealant deposits silica-based polymers that bond to a wet surface and form a hydrophobic layer as you rinse. That layer forces water into beads that roll off, carrying dirt and contaminants with them, which reduces spotting and streaking after rain or washing.

• Water-activated SiO2 formula for instant beading
• Forms a low-surface-energy coat that sheds water and grime
• Compatible with paint clear coats, glass, and wheels

How simple is the application process for regular maintenance?

Application is fast and suited to routine washes: work in sections, spray onto a clean, wet area, then rinse off and dry with a microfiber towel. No buffing or special tools are required, making it a practical top-coat after every wash or whenever you want extra water beading.

• Spray on wet surface in manageable sections
• Rinse immediately, then dry with a clean microfiber
• No abrasive polishing or clearcoat removal needed

What kind of protection and longevity can I expect?

Under normal conditions you can expect up to six months of enhanced water beading and resistance to water spots, dust accumulation, and light road contaminants. Longevity depends on exposure, washing frequency, and driving conditions, but the SiO2 layer gives noticeably better hydrophobic performance than standard rinses.

• Up to six months of hydrophobic protection
• Reduces water spotting, dust buildup, and light dirt adhesion
• Works on paint, glass, wheels, and exterior trim

Will this product harm my vehicle’s existing coatings or finishes?

No—303 engineered this spray to be used as a maintenance top coat that complements existing clear coats and sealants. It is intended for use on clean, wet surfaces after washing and rinses away cleanly, leaving behind a slick, glossy finish without stripping other protective layers.

• Safe over clear coats and factory finishes
• Non-abrasive, rinse-off application minimizes risk
• Leaves a glossy, slick surface that enhances appearance

Who is this for? 303 Products Spray & Rinse Ceramic Sealant is ideal for car owners who want a fast, low-effort way to add ceramic-style beading and shine between professional coatings. It suits weekend detailers, fleet managers needing frequent rinses, and anyone who wants improved water repellency without complicated application steps. Keep in mind that environmental exposure and washing habits affect durability, so periodic reapplication will maintain optimal performance.

Usage tip: Always apply to a thoroughly clean, wet surface and work in shaded or cool conditions to avoid drying spots. Store the bottle as indicated — 303 Products recommends product use within two years from the bottle’s packaging date (YYDDD).
