Hi Chris(Edu),
IMHO, it's always best to polish with a machine and apply wax or sealants by hand.
If you take polishing slowly and methodically and learn your technique on loose panels (rather than your own), then there's little to worry about but do follow these important rules:
1) ALWAYS USE THE LEAST AGGRESSIVE POLISH
2) NEVER STAY IN ONE POSITION TOO LONG
3) BE CAREFUL AT SEAMS AND EDGES
Just remember, applying a 'bit more polish' is a LOT easier then applying a 'bit more paint'
For someone new to polishing, a Dual Action/Random Orbital Polisher is safer than a Rotary but best to get one with reasonable power and a range of speed settings.
I used to machine polish all my own and others cars for pleasure and shows and did it for years prior to my illness (though sadly I'm not up to it now).
When I started it was with the Porter Cable 7424, which served my needs very well (although it needed a transformer for UK use) - there are others available nowadays, like the
DAS 6, which I'd probably go for if I was buying today.
You can spend more, on something like a
Flex XC 3401 DA with positive drive and random orbit but unless you're using it professionally and need more cutting power I really don't see the point.
My approach was always the same: A thorough two bucket wash, clay all panels, tar remover where necessary, wax remover, mask off lights and plastic trim, and polish small sections (2ft x 2ft), roof downwards, using a hand-held fluorescent tube (old school) to check progress - there are better Xenon light units now.
In the old days I used to always use Sonus Pads (Yellow/White/Orange), a water spritz and wet bucket for pads, Farecla G3 for deeper swirls (depending on paint condition), followed by 3M Finesse-It, a through clean up, followed by 3M Hand Glaze and two coats of Zymol Atlantique by hand.
Times have changed however, so if I was doing it now I'd probably do the wash/decontaminate process above, check the paint thickness with a Paint Thickness Guage, then 3M Perfect-It (if the car had major marks), followed by 3M Finesse-It, a careful clean-up, then CarLack68 Nano (acrylic sealant) and finish with a couple of layers of Pinnacle Souveran Paste.
If you're looking for a good guide to polishing (and don't mind reading rather than watching) then I highly recommend this guide from
Detailing World
Last but not least, enjoy the fruits of your labours!!
These pics are of my 54 plate Touareg back in 2006, after a good polish - in the side on pic I'm about 15 feet from the car. Happy days
Hope that's been some help.
