Can someone explain what a sealer is for?

I`m trying to figure out exactly how to use a sealer. I have gathered that it goes on after polishing, and before wax, and it may take 24 hours to cure. Is that correct? How is a sealer applied? What happens if you *don`t* use a sealer, and just put wax on after polishing?

You do not have to use a sealant if you do not want to. It will protect the paint longer than a wax though. Yes, sealant before wax. Most sealants should be applied thin, either by hand or PC, I apply by hand, do not have a PC.
