McKee's 37 Clay Lubricant provides a barrier of lubrication for a clay bar or clay mitt to work as intended without scratching or marring the paint.  Compared to a car wash soap or detail spray, Mckees 37 Universal Clay Lubricant will not cause the clay bar or clay mitt to deteriorate over time.  Mckees 37 Universal Clay Lubricant actually extends the working life of the clay bar because its water-based formula contains no solvents.  

First you might be asking, what is a clay bar and why do I need it?  Detailing clay creates a smooth slippery surface by removing bonded contaminants such as paint over spray, bird droppings, bug splatter, and other topical pollutants that are not removed during the washing process.  Using a clay bar is as simple as spraying the lubricant onto a clean panel, and rubbing the bar back and forth until it glides freely.  Then, buff off the lubricant with a towel and move to the next section.  Mckees 37 Universal Clay Lubricant wipes off without streaking or smearing, plus it smells great!

Mckees 37 Universal Clay Lubricant is safe for all exterior surfaces.

Directions:

On a freshly washed vehicle, mist a 2 ft. x 2 ft. area of paint with McKee's 37 Universal Clay Lubricant.

1. Gently rub the clay bar back and forth across the wet area only. It will grab initially. This is the clay grabbing contaminants that protrude above the clear coat surface. When the clay glides freely, the surface is clean.
2. Wipe off the area with a clean microfiber towel. Use the clay lubricant to remove any remaining clay residue.
3. Before moving on to the next section, inspect the clay to see if it appears soiled. If so, reshape the clay to reveal a clean side. If you drop the clay on the ground, discard it.
4. To store the clay, moisten it with clay lubricant and seal it in a plastic bag within its plastic case.
