Some detailers use a base of sealant protect and caranuba over that to give a better wet look.
Good sealants are the zaino line, Klasse Sealant Glaze and chemical guys' jetSEAL. If you choose to wax, then chemical guys' 5050 is a great option.
You should waz/seal depending on a lot of things. First, what product are you using. Wax (caranuba) can last for maybe a month. You won't need to seal for at least 3 months.
It's also important how often you wash the car, what shampoo you use and what kind of treatment does the paint receive (snow, salt, etc...). Hope that helps.
+1. This guy knows what he is talking about.
And for those that bought the $175 zymol concorse wax, try chemicalguys 50/50 for $50 and tell me if you see a difference worth over $100, and thats if you see one at all.
