Dogslovetrucks is correct. I use the Meguiars products and so do many other people. I get a good shine and water beads right up in rain and the wax lasts. Make sure that you get just wax and just polish. Check out the website it will explain a lot and even will help you so that your truck's skin lasts longer.
Many others use different kinds of wax. I would use what works best for you.
