The top rated car wax and polish is Black Magic, according to Cars Direct. Many users at professional car shows also use wax and polish from Mothers and Meguiars.
Black Magic car polish is available from PepBoys for $3.90, as of 2015. Some of the features of Black Magic include rich conditioning creams, optical brighteners and easy-to-use application by hand.
When applying Black Magic, pour a small amount onto a soft applicator and apply the wax in a circular motion. The wax should dry until it becomes hazy. Remove it with a cotton cloth or a microfiber towel. The cloth should be turned frequently to prevent the build-up of residue.
