First, claying; its really simple. You'll need one of those plastic spray bottles to mix the solution in. The solution is simple; 2 capfuls of carwash with water.
1. Wash the car with 'Dawn' to remove the old wax.
2. Leave the car wet
3. Spray an area about 6" X 6" with the solution and lightly move the clay across the surface (front to back on hood/roof/trunk area - top to bottom on sides) periodically checking the clay for debris (it will turn black as it removes the contaminants) and kneading the clay to a clean spot as necessary. Continue to do the entire car. It should take no longer than 30 -45 min.
4. Re-wash car and dry
5. Begin polishing
Its truly a simple process and very easy to use.
