Frequently Asked Questions
What is "surface reset"?
OVERcoat pH+ is a strong car shampoo that is designed for maximum cleaning efficiency against oil, bird droppings, insects and other stubborn grime, being capable to reset any surface.
Is strong car shampoo safe to use?
Although it has a strong effect, it is pH balanced to prevent damaging the clear coat.
Can it be used on coated vehicles?
We recommend using the shampoo in a diluted form on coated vehicles. Depending on the type and hardness of the coating, there may be a slight reduction in water repellency. However, high-quality and high-hardness coatings can be safely used without issues.
If the repellency weakens, you can restore the performance by applying OVERcoat ULTRAviolet as a top-up in the final step.
