Personally, I think you’d be wasting your money if you go down that route. All you need to do is to get a pro to polish your car once, then apply a coating of whatever takes your fancy. If you’re then happy to do the basics yourself, and do it well, you simply won’t need to hire a pro again.
Saying that, waxing really isn’t something I’d ever pay someone else to do, not when you can do it yourself in an hour once a month (and that’s dragging it out!).
