CSII Stage 2 coating lasts for 18-24 months, and is the perfect entry level coating for customers new to coatings or are on a budget. Stage 2 Coating, when applied professionally, will produce 5,000 nanosized resin particles over one square inch. These particles lock into the paint surface of a vehicle and seal it. No waxing is required for 18-24 months. When our paint protection product is applied, any acid rain fallout, bird droppings, or tree sap will not harm the coating.
