Don’t be fooled by some companies that lead you to believe that it is ONLY the UV protection in a wax that protects your car’s finish from fading and failure. This is dishonest and simply not true.
UV protection in a car wax formula is only an extra-dose of preventative maintenance and not the end-all, cure-all that some of these companies lead you to believe.
UV protective agents for paint is much different from UV blocking ingredients for human skin. The two formulas are nothing alike and work in dramatically different ways. There is no correlation between the ratings applied to the different levels of sun blocking protection for products intended for use on human skin and the ingredients available for use in an automotive wax formula. Sad to say, much of what you see advertised about the protective qualities of most car wax products on the market today is simply over-exaggerated hype used to separate you from your hard earned dollars.
If you wash and wax your car regularly the paint will be protected and will not suffer major UV damage over the normal course of its lifetime.
