The life expectancy of a coat of wax depends on many things:

• How well the surface was prepared to accept the wax
• Local environment (normal conditions and extraordinary events)
• Condition of paint
• Number of hours exposed to outside conditions
• Quality of the wax used and method of application
• Quality of car wash used (dish soaps will remove wax)

Your best option in all cases is to rely on the highest quality surface care products available and to try and match the wax to the surface to which you are applying it in conjunction with the environment it is most commonly exposed to.

For example: If your finish has been severely neglected, you will achieve the best results using a three step paint restoration system such as Meguiar's Deep Crystal System, which includes a specially formulated:

• Paint cleaner
• Pure polish
• Pure wax

Should you prefer not to use a three-step process to restore it, then you'll get your best results using one of Meguiar's one-step Cleaner/Waxes, such as Meguiar's Cleaner/Wax or ColorX^®.

Because Meguiar's Cleaner/Waxes clean, polish and protect in one easy step, the cleaning action will create a surface in which the protective waxes can better adhere. Thus the wax will last longer than a wax that has no, or inadequate cleaning ability. Meguiar's guarantees that under identical conditions, "Meguiar's waxes will outlast the competition."
