Don't be afraid to use a DA chaps, it's the rotary polisher instead that needs to be used with care (or by the pro detailers). I've had my DA for maybe 10 years and have used it on all our cars over the years, it's priceless, does an excellent job of polishing (saves the pain you get with hand polishing). Because the DA oscillates, you can't burn through the paint.
I need to clay the car again as recently had wheel hubs sprayed and now have got some small overspray on the body - arghh! After claying, will then use LimePrime Lite and finish with Swissvax Mirage which gives a lovely finish. A nice technique I've picked up from detailing world is to apply the wax on the palm of your hand which works well and prevents from applying anything more than a film of wax - also a nice way to get to know your Maserati better.... ;-)
