Car manufacturers usually recommend that you don’t wash the car for 30 days in order to maintain a fresh coat of paint.  So, if you have just had your car painted, I would advise you to wait until you are sure that the print quality won't be compromised. With regards to fresh paint, you shouldn’t have it waxed until a full 2 months after the car has been painted.  It is advised to get your car waxed since waxing provides an extra layer of protection and maintains the finish of the paint underneath. The wax finish will also protect against bird droppings and dead bugs, which are acidic in nature and can ruin the paint finish of your car.
