Mckee’s 37 – Coating Prep Auto Wash

McKee’s 37 Coating Prep Auto Wash is a powerful detergent that strips remaining traces of previously applied waxes and sealants, leaving your vehicle squeaky clean for the next step in detailing

By breaking down old waxes and silicone oils, the next step you perform in the detailing process (clay, polish, coat) will produce superior results.

McKee’s 37 Coating Prep Auto Wash is infused with highly refined alkaline detergents that effectively deep clean your paint without drying it out. Formulated without acids or phosphates, you can trust that Coating Prep Auto Wash is 100% safe for all exterior surfaces. This high-foaming formula encapsulates dirt and grit particles, helping to prevent wash-induced swirl marks and scratches.

It’s common knowledge that the cleaner the paint, the better your wax, sealant, or coating will adhere. That’s why we formulated a special auto wash that’s 3 times as powerful as a regular soap, helping break down and remove trace residues of previously applied waxes and sealants. This improves the performance of your clay bar or polishing compound. Washing your vehicle with McKee’s 37 Coating Prep Auto Wash is the first step in a proper detail.
