Rightlook.com's blue Light Duty Detailing Clay is great for removing light paint over spray, environmental fall-out, and mild rust deposits from vehicles that are detailed often. It is strongly recommended that Rightlook.com's Detailing Clay be used on every vehicle prior to applying wax or sealant. Directions: Start by washing and drying the vehicle as usual. Spray the paint surface with Rightlook.com's Clay Lubricant and rub the clay bar back-and-forth across the surface until the contamination is removed. Continue until the entire vehicle has been covered. Caution: If a clay bar falls to the ground or comes in contact with dirt, sand, or debris, you must discard the clay as debris will be lodged in the clay. Using clay that has been contaminated by dirt or sand particles may cause damage to a vehicle's finish. Tip: For best results, divide each clay bar into 3 sections. Use one third of a bar to work on a small area of the vehicle at a time. This method allows you to use only the amount of clay that you need to get the job done. Also, if you drop one section of your clay bar, you still have 2 more sections to use.
