Removing the swirl marks was a combination of products, the previous owner had not taken good care of the car as it was a company car, so I had my work cut out for me when I bought it.
The entire procedure is as follows -
Wash the car,
Clay (3M Clay, as listed previously) the car to remove imperfections.
2nd wash, rinse & chamois dry
clean door jambs, bonnet and boot sills and fuel filler recess.
Machine polish - Pinnacle XMT Fine Cut over entire car
Machine polish - Pinnacle XMT Ultra Fine Cut over entire car to restore shine
Wash car to remove polish compound and chamois dry
Apply Swissvax cleaner fluid to prepare surface for waxing
Apply Swissvax Saphir Wax & Buff off
Apply Duragloss Aquawax as final sealant
This whole process takes the best part of a day, but once the car has been prepared correctly it takes minimal care to keep it in this condition. Washing with a good mitt and clean water and waxing every few weeks is sufficient.
Also, if you are considering a machine polish, DON'T get those polish/buff machines from supercheap/autobarn etc. They are not up to the task, and will do more harm than good. Invest in (or borrow) a decent Random Orbital Sander such as a GMC RO150 from Bunnings for about $140 and fit it out with a good pad. Lambswool pads will make more marks so avoid these- they are used for panel beating type jobs or heavy paint correction and are not suitable for correcting light swirls in paint. Buy a quality Foam pad such as a light/medium cut Meguairs pad. I use CCS pads from Waxit, although these are quite expensive if you are on a budget. XMT Products are intended for use with a machineso if you want to hand polish, use the meguiars foam applicator pads with Autoglym Deep Crystal Polish, and work the product in lines, not circles one panel at a time.
TIP - to remove polish/wax residue from your plastic or rubber trim is to simply rub them off with a soft pencil eraser. Works 90% of the time.
Just for interest, below is a comparison on my SV6 taken last week (3 days after washing). It rained just before I left for work, and as you can see less than 20 minutes at 60-80kmh is plenty to get the rain to sheet off with minimal water spots remaining. This is with an application of Aquawax.
