Polishing machine, any recommendations?

(1/4) > >>

Sharman:
Fancy treating myself to a polishing machine and heard good reports about the Meguiars machine, but they seem a little expensive(compared to Halfords). I was going to pay for "Shine" to do my Black pearl GTI, But at £75, I'm tempted to buy a machine and do it myself. I'm just a little worried how skilled a job it is, as I don't want to make a pigs ear of it! Also, I can hire the meguiars for £30, but then need the polish etc. Any ideas of what works best on Black pearl? Decisions, decisions!!

keith:
I used the Megs G220 to do my paintwork with some dodo juice lime prime and it brought the flakes out really well on my steel grey this was just a quick hit but very impressed far better results than by hand.

I've machine-polished my own car. It's not difficult to get rid of light swirls, just time-consuming. Random deep scratches are harder to get out.

Both Megs G220 and Kestral DAS6 or whatever it's called are both good for beginners. Get some decent pads and polish. Also make sure you prep the surface beforehand (decent wash, clay the car too).

Sharman:
Great advice about claying beforehand, I've used clay bar before with amazing results. Just out of interest, how many times can you machine polish, before getting too close to the paint? Obviously your're taking laquer off to remove the swirls.

stealthwolf:
The best way would be to use a paintdepth guage to measure the paint thickness. Ideally you should not be removing more than 1-2 microns I think. Typically on a VAG car, expect around 110-130 microns, some of which will be primer/paint as well as lacquer.

Polishing should not be done more than twice a year for this reason.
