I would follow zymol's directions in terms of applying this wax. It is important that you work the wax a little with your fingertips and then apply it to your surface by hand.
You can either use your bare hands, or if you are afraid of marring, then you can have a choice of using latex or disposeable cotton gloves. Never use clear plastic or nylon gloves, because they will induce marring (trust me!).
Zymol says that you should wait 5 minutes before taking the wax off, but I've found that by the time you finish applying the wax on the surface (don't bite off too much at first; Just half a hood or a fender at a time until you get the feel for it) that five minutes would've passed. You could start buffing the wax off as soon as you finish applying it to a surface. It has also been very beneficial to me that having at least two buffing towels (I use three) is the best way to take off the wax residue, as you can take it off with light to moderate hand pressure and not risk putting excessive pressure to the panel, which could cause marring.
After you have buffed off all of the paste, you can come back and do a final wipe with your best towel, and you can do it dry or with atomized water.
Good luck. Vintage is a sensational wax.
