I don't use wax. I use modern polishes developed for specific finishes. I use a couple of things. When simply "touching up" I use Zaino Grand Finale Spray Seal. For "full" cleaning, polishing and sealing - Zaino Show Car Wash, Zaino Pro World's Best Car Polish alternated with Zaino Show Car Polish then Spray Seal. My cars all present with a "show" quality finish.
Meguier's and other companies have similar products and are great quality as well.
