There is so much information and an insane amount of product choices when it comes to waxes and polishes..  It is extremely difficult to figure out with what and how to do it, but polishing a car isn't as hard as you think.  Prep the surface, tape the trim, get a random orbital polisher and some pads, and you can see some great results.  The products below were chosen after trying dozens of products over the course of years. These are the products I use on my cars, so naturally I offer them here.
