Selecting the Correct Clay Grade (Fine / Medium / Heavy)

Choosing the correct clay grade depends on your vehicle's paint condition and detailing goals. Fine clay is ideal for light contaminants and sensitive surfaces, medium clay for moderate contamination, and heavy clay for industrial fallout or heavy debris.
