It depends on climate, if car is garage kept and where you drive (dusty or clean conditions and air ect). I have a 2009 Pontiac that is parked outside (typically in the sun but sometimes in shade if I can) In Ohio where summers can get hot and winters can get cold. I always wax my car in the Spring (March-April) and always a second time around the end of September (just before it starts getting cold/chance of snow). Again always do a good wash before waxing your car. It is not to much upkeep twice a year maybe takes me an hour or two. (always wax in shade if you are able too- I pull it in my parents garage-) This is not much short term again as it is long term gain. 11 years and my paint is still in very good condition, because of the wax is a barrier between the sun and the clear coat. Also after I wax my car I wait a few weeks before I think of washing it again. (If you do decide to wash your car weeks or months after you wax your car you should notice the soap/water sometimes even rain washes off the car like smooth silk; and no reason to apply another wax until you feel necessary. (most experts recommend 6 months in between wax coats or twice a year). Hope this helps!

I would still wax it Justin B. Assuming your clear coat is decent, the wax will add another layer of protection to your paint.

Do not waste your money like I did! The only color that may work is black. Good luck.

I was wondering that too

Some glass scratches can be removed or reduced.
