Auto Finesse | Aqua Coat Hydrophobic Rinse Aid 500ml

Designed to enhance water beading, protection, and gloss quickly and efficiently during the wash stage, this advanced SiO2-based hydrophobic rinse aid bonds instantly to create a glossy, protective layer. It offers a modern, fast solution for applying a ceramic coating in seconds, without requiring major changes to your usual wash routine. Simply mist Aqua Coat after rinsing away contaminants during your contact or decontamination wash, then rinse again to coat your entire vehicle.

SiO2-based ceramic coatings use silicon dioxide, commonly known as silica or quartz, which is a key ingredient in glass and ceramic glazes. This natural compound forms strong chemical bonds with almost any surface, creating an incredibly hard barrier resistant to moisture, grime, chemicals, and environmental contaminants. The durability of SiO2 protection is one of the main reasons ceramic coatings are considered the best for long-lasting performance.

On a molecular level, the SiO2 layer bonds to the surface, smoothing out microscopic imperfections and creating a smooth, hydrophobic barrier. This prevents water, dirt, and other contaminants from sticking, while also protecting the surface from corrosion, oxidation, and fading. Surfaces treated with SiO2 coatings repel foreign particles, causing them to either slide off or rest on top without bonding, making future cleaning much easier.

SiO2 coatings are also completely clear, allowing light to pass through and reflect evenly, similar to the effect of a car wax. This results in a deeper, glossier finish.

Auto Finesse Aqua Coat is safe for all exterior surfaces, including paint, trim, wheels, and even vinyl wraps. It can be used as a standalone detailing product to apply an SiO2 coating or as a quick maintenance top-up to extend the performance of existing SiO2-based ceramic coatings, such as those in the Caramics Protection range (including Paintwork Protection Kit, Glass Protection Kit, and Wheel Protection Kit). Remember, a little goes a long way—just mist over the surface and let the product do the rest!
