Mother's Carnuba Cleaner wax is a bitch, like waxing with a hard candle, but really nice when it comes off. That's one extreme in difficulty.
imo, just pick a nice Meg's cleaner wax OR an actual paint cleaner if your finish is rough. Buff it hard w/ a lot of water. Wipe off the dry wax or wash it again if using paint cleaner/polish.
Go over it with the REALLY easy SynWax, done. SynWax is so easy you can hit it again anytime in like an hour. Rejex is good too. Just a complete hand wax, nothing fancy. Cars are made to serve you, not you serve it.
