This Chemical Guys Heavy Duty Clay Bar and Luber Synthetic Lubricant Kit, is perfect for water spot removal. This product will leave a silky smooth finish with a mirror-like appearance. It is safe for all aluminum, chrome, glass, paint, and all other pained finishes.

Step 1: Start with a Clean Car

Before using clay, make sure that your car is fully washed from any loose dirt.

Step 2: Soften the Clay

Grab your clay in your hand and squeeze it until it is a pliable disc. The warmth of your hands will soften the clay as you work on it. Once it is soft and ready, flatten it into a circular shape.

Step 3: Spray the Lubricant

Generously spray a lubricant on a section of water spots you will be working on. A section should be big in order to prevent damaging the paintwork.

Make sure that your section is not only just misted, but saturated with the lubricant. In addition, spray some of it on your clay disc for some extra lubrication.

Step 4: Start Working with Clay

Slide the clay back and forth over the lubricated area. Flatten your hand and pin the clay disc gently against the car with your fingers. Rub in side to side or up and down motion. Do not rub in a circular motion since this might create scratches.

Add more lubricant if you feel like clay is sticking to your vehicle's surface.

Step 5: Work on Different Areas

As you move along to different parts of your car, you may notice that the clay is getting dirty with contaminants. When that happens, fold the clay disc over and flatten it out so you have a clean surface.

Repeat these steps until you get rid of all the spots.

Step 6: Wash Off the Lubricant

Wipe the area with a clean and damp towel to remove any residue. Wipe the area thoroughly but not aggressively.

Step 7: Apply Wax

After using clay bar, it is recommended to use a paint sealant or wax protection. Waxing or sealing protects the paint from future water spot contamination and from any corrosion.
