I use Optimum No Rinse and Optimum Spray Wax exclusively. I clay and wax every spring and fall (Mother's clay kit). 4 years later (4 salty slushy Nova Scotia winters I might add) and my 4Runner basically looks as good as the day I bought it. The paint is glossy as can be. I use is Optimum No Rinse on ALL exterior surfaces including the wheels. Sometimes I use a bit of tire shine if I'm feeling up to it. The best product I've ever used.
