What should I consider before making a choice in which car wax to use on my 1989 Dodge Caravan?

Giving you car a wax is the best way to preserve the paint job. Newer cars don't need as much wax to shine as old cars do. Liquid waxes generally offer the best protection and gloss. Black Magic Wet Shine Liquid Wax should be a great wax to use on your car.
