Koch-Chemie WetGloss is a premium spray-on, rinse-off wet sealant designed to add incredible gloss, slickness, and hydrophobic protection to every exterior surface of your vehicle. Whether you're maintaining a ceramic coating or protecting uncoated paint, WetGloss delivers professional-level results in just minutes with virtually no effort.

Key Features & Benefits

🔹 Spray-On, Rinse-Off Application – Simply spray onto a freshly washed, wet vehicle and rinse away for instant protection without buffing or curing.

🔹 Extreme Water Beading – Creates a highly hydrophobic surface that sheds water quickly, helping keep your vehicle cleaner between washes.

🔹 Deep Gloss & Slick Finish – Enhances paint clarity with a smooth, glossy finish that makes colors pop while reducing surface friction.

🔹 Perfect as a Standalone Sealant or Ceramic Coating Topper – Use WetGloss by itself for several weeks of protection or refresh the hydrophobic performance of existing ceramic coatings.

How to Use

Step 1: Thoroughly wash the vehicle to remove dirt and contaminants.

Step 2: Leave the vehicle wet after the final rinse.

Step 3: Spray WetGloss evenly over one section at a time while the surface remains wet.

Step 4: Immediately rinse thoroughly with a strong stream of water to activate the sealant.

Step 5: Dry the vehicle completely using a premium drying towel to prevent water spotting and reveal maximum gloss.

Pro Tip: Apply on cool surfaces out of direct sunlight. Pair WetGloss with a quality pH-neutral shampoo during maintenance washes to maximize durability and preserve its outstanding hydrophobic performance.

Why We Love It

At Car Supplies Warehouse, we love Koch-Chemie WetGloss because it delivers one of the fastest ways to add serious gloss and water repellency after a wash. There’s no wiping, no buffing, and no complicated application process—just spray it onto the wet vehicle, rinse it off, and dry. It’s an excellent maintenance product for ceramic-coated vehicles, but it also performs incredibly well as a standalone paint sealant. The slick finish, impressive water behavior, and ease of use make it one of our favorite "wash day upgrades."
