Which of the following waxes provides the least duration of protection?

The 90-Day Wax is designed to offer a shorter duration of protection compared to other wax options, such as the 6-Month Wax. The naming convention reflects the expected lifespan of the protection it provides, with the 90-Day Wax offering a good level of shine and protection for a limited time, ideal for customers looking for immediate visual enhancement and protection against elements for a shorter period.

In contrast, the 6-Month Wax is formulated to endure for a longer duration, thus providing extended protection against environmental factors like UV rays, dirt, and contaminants. Customers may choose the 90-Day Wax for a quick refresh or if they plan to frequently maintain their vehicle's appearance, but if they desire longevity without frequent applications, the 6-Month Wax is the more appropriate choice. Therefore, the 90-Day Wax indeed provides the least duration of protection.
