Koch‑Chemie Hydro Foam Sealant S0.03 is a high-gloss, wet-applied sealant that combines paint protection and shine enhancement in a single, easy step. Designed to be used immediately after washing while the vehicle is still wet, it creates a deep, velvety gloss on paintwork, glass, and plastic trim. With powerful hydrophobic properties, this sealant significantly improves water beading and runoff—helping keep your vehicle cleaner between washes.

Formulated with UV inhibitors and surface conditioners, Hydro Foam Sealant also protects plastic components and convertible tops from fading and brittleness over time. Its fruity cherry scent adds a pleasant sensory touch to the application process. Ideal for professionals and enthusiasts alike, this sealant is an excellent maintenance product to be used weekly, delivering impressive results with minimal effort.
