As a bonus, if you've clayed and polished your paint beforehand, it really will look like someone poured liquid glass on your car. If you have no idea what I mean when I say things like claying your paint, don't worry about it. Just use a sealant and you'll be very happy with the results.
By the way, "wax" is not a catch-all term for making your car shiny
A quick gripe from a devoted car guy: people frequently use brand names to identify other similar products -- think "Kleenex" instead of "tissue." That's not something you can do here, because wax and sealant are so very different. If you say you're "waxing" your car, I'll just assume you mean you're using carnauba wax in an attempt to get that yellowy deepness. If you mean it in any other way, you're misusing the word and opening the door to confusion.
Sealant's not the future, it's the present. There's even cooler new stuff on the horizon, but let's save that for another day, shall we?
