Hello Jeff - Just brought my new car city 09 (bold beige) to your shop for new car paint protection. Have some questions which I forget to ask... When will the sealant last? Do I need to wax the car or car wash with water is enough? Btw during evening, just noticed that my trunk have some sort of stain from the sealant once reflected a light coming from a lamp post. However you need to view sideways to see it. But during morning its invincible. Ano kaya yun?
