Sun Blocker Auto Finish is the best car polish and paint protection available anywhere. It is a substitute for wax, but it protects and maintains the shine of a car at least 20% longer than regular car wax. It is sold in a bottle that is adequate for one application to one car. Regular wax, which is sold in a container that is enough for two applications, costs about $4.00/container. Some cars (about half) have oxidized paint (no shine) at the time wax is to be applied, requiring cleaning with an oxidation cleaner before one can apply regular car wax. Oxidation cleaner costs $2.50 per bottle (good for one application) and can be applied in about the same time required to apply either an oxidation cleaner or regular wax, about two hours. An additional advantage of Sun Blocker, however, is that it both removes the oxidation and shines the car's surface in one step. Consequently, Sun Blocker can be applied directly to a car's surface that is already highly oxidized. 1.
