A. This may have been true a long time ago, but with the new modern acrylics and enamels, your new car's finish needs tender care immediately. Be careful to wash your car properly. Most new cars are treated with a clear-coat finish. So it's important that you exercise extreme care - especially when washing your new car for the first few times. Many initial washing errors result in water-spots, setting stains and loss of luster. Without the benefit of layers of protective coating that your car will receive over the years, mistakes made during the first few washes may not be correctable.
Should you decide to wax your car, use a wax that's compatible with your paint. Check your owner's manual and the wax's label for instructions.
The best advice is to trust your car's finish to a professional from the beginning.
