MCKEE'S 37: WORLD-CLASS AMERICAN CAR CARE

Born from decades of experience in the detailing industry, McKee's 37 was founded by Bob McKee with a singular vision: to manufacture world-class, uncompromising American car care products. Rather than relying on heavy marketing fluff or complicated, multi-step systems, McKee's 37 focuses on proven, user-friendly chemistry that bridges the gap between passionate weekend enthusiasts and high-volume professional detailers. Every formula is designed to solve real-world detailing problems efficiently, effectively, and safely.

The House of Rags carries a curated selection of McKee's 37 heavy-hitters, engineered to cover every stage of your detail. Start from the ground up with their legendary Tire & Rubber Rejuvenator and Gentle Wheel Cleaner to strip away deep browning and road grime. For paint correction, the BEAST Compound delivers heavy defect removal while finishing down like a polish. When it comes to the cabin, their unique Leather Shampoo 70/30 cleans and conditions in one simple step.

Where McKee's 37 truly dominates is in surface protection. For ultimate convenience, the legendary Hydro Blue SiO2 Coating offers intense water-beading with a simple spray-on, rinse-off application. If you are looking for maximum, multi-year durability, their advanced Graphene Pro-Coat 2.0 and Hydro Graphene Ceramic Coating utilize the latest in carbon-based technology to provide jaw-dropping gloss, extreme chemical resistance, and unmatched slickness.

MCKEE'S 37 FAQs

What makes McKee's 37 different from other American detailing brands?

McKee's 37 is built on the expertise of Bob McKee, a pioneer in the detailing supply industry. The brand is known for formulating "smart" chemistry—products that perform multiple functions or drastically cut down application time without sacrificing professional-grade results. All products are proudly manufactured in the USA and are extensively tested in real-world detailing shops before hitting the market.

How do I apply the Hydro Blue SiO2 Coating?

Hydro Blue is one of the easiest ceramic sealants on the market. After washing your vehicle and ensuring it is completely out of direct sunlight, leave the paint wet. Simply spray Hydro Blue directly onto a wet panel (one panel at a time) and immediately rinse it off with a strong jet of water. The water pressure activates the SiO2 polymers, instantly bonding them to the clear coat for durable, high-gloss water beading.

What is the difference between Hydro Graphene Ceramic Coating and Graphene Pro-Coat 2.0?

Graphene Pro-Coat 2.0 is McKee's flagship, professional-grade coating. It comes in a small glass bottle, is applied with a suede applicator pad, and cures to form a hardened, multi-year sacrificial barrier with extreme 10H hardness. Hydro Graphene Ceramic Coating, on the other hand, is a highly durable spray-and-wipe sealant. It is much faster to apply and is perfect as a standalone 6-to-12 month protectant or as a maintenance topper for the Pro-Coat 2.0.

Why should I use the Tire & Rubber Rejuvenator instead of normal car soap?

Tires naturally exude antiozonants (which turn the rubber brown) and collect heavy traffic film that regular car soap cannot break down. Tire & Rubber Rejuvenator is a highly specialized, heavy-duty cleaner that instantly melts away tire blooming, old greasy silicone dressings, and road grime. A perfectly clean, bare tire is the only way to ensure your favorite tire shine will properly bond and not sling off onto your paint.

What does the "70/30" mean in the Leather Shampoo?

The "70/30" refers to the specific formulation ratio: 70% cleaner and 30% conditioner. This means it has the active cleaning power to lift body oils, denim dye transfer, and daily grime out of the pores of your leather, while simultaneously laying down a 30% blend of natural oils and lanolin to keep the hide soft and supple. It saves time by combining two interior steps into one.
