Mckee’s 37 – Hydro Blue SiO2 Spray Sealant Concentrate

Protecting your vehicle has never been easier. McKee’s 37 Hydro Blue is an advanced SiO₂ coating that delivers 3 months or more of protection with a simple spray-on, rinse-off application. No traditional waxing techniques or lengthy application processes are required.

Designed for use as a standalone protective coating or as a booster for existing paint, glass or wheel coatings, Hydro Blue provides a slick, glossy and highly hydrophobic finish across all exterior vehicle surfaces.

Formulated with advanced SiO₂ technology, McKee’s 37 Hydro Blue forms an electrostatic bond with exterior surfaces to create a durable protective layer. This coating delivers exceptional gloss, slickness and hydrophobic performance, producing impressive water beading and sheeting.

Suitable for paintwork, wheels, glass, chrome and plastic trim, Hydro Blue helps keep surfaces cleaner and easier to maintain. Its UV absorbers also provide additional protection against sun-related dulling and fading.

Only a small amount of concentrate is required to protect a full-size truck or SUV, making Hydro Blue an economical solution for both professional detailers and automotive enthusiasts.

Developed in South Florida, Hydro Blue is formulated to perform reliably in bright sunlight and humid conditions without unwanted streaking. Whether used as standalone protection or to boost an existing coating, McKee’s 37 Hydro Blue makes vehicle protection fast, simple and effective.

Hydro Blue is water-activated, allowing you to apply protection without traditional waxing methods. For best results, use immediately after washing your vehicle while the exterior surfaces are still wet.
