If you have a metallic paint job wash with a fairly mild detergent and then use some suitable solvent to remove tar spots. A -95 with no wax job seems a long time and the paint can be a bit oxidized if it´s not metallic which has a clear top coat. If not metallic, you can use a special cleaner with some rubbing action to clean and polish the paint before waxing.
Apply wax as per direction on the container. Let dry as per direction. It helps to do a limited area at a time, say 3-4 square feet or so.
