First/Second attempt with DA..
Boothy:
So if I've used the PF2500 / PO 203 S and still got swirling with a SFX-2 pad I should move up right? To a more aggressive pad or polish or both?
matsu:
and this is why my brand new da has stayed in the box with all the polishes....just not had the courage to have a go...even on my sons old clio lol :ashamed:

What did you do to assess the swirls? Most pros use an IPA wipe down to remove the polish residue. Polishes can fill in a lot of swirls so you need to remove the residue to see the final effect. You also need decent light sources to detect swirls from different angles and brightness/intensity.

Initially I couldn't get the polish to break down but I was told I was using too much so used less on the next panel which I think has come up ok?

Depending on the panel, I use two or four pea-sized blobs. Any more and you can't work the polish properly, or it takes longer to do so.

As above, depends on the aggressiveness. I think you should have started with an SFX-3 pad, not SFX-2 and then worked your way from there. Read the guide - you need to use the least aggressive polish and least aggressive pad first. In your case, FG500 is the most aggressive Menzerna polish so no surprise about what happened.
I think I'd have started with SFX-3 and UF5000. If that didn't work, then move to the next aggressive polish - either SF4000 or FF3000. If no joy, then switch the pad. I wouldn't go beyond PF2500 and SFX-2 (though TBH you should have had a decent response to P2500 and SFX-3).
List the polishes that you have. Have a look at the Menzerna chart. FG500 is the most aggressive and not something I'd use IMO. I wouldn't go beyond a cut of 6 - otherwise you're looking at getting a pro to do a good job of it.

I should have said in my original post - initially I did use a the FF3000 (PO 85 U) with the SFX-3 polishing pad but it did nothing so I upped to the PF2500 (PO 203 S) with the same pad and that, I though, had done the business. To check this I wiped down with a 50:50 IPA solution and then inspected with the poxy'est light source ever, the LED on the back of my mobile phone. I did think however that it had removed the vast majority of swirls but later that day in bright sun I could still see them.
So the next day, and this is where this thread starts I decided to use the PF2500 but with the SFX-2 pad to see if that would get rid of more swirls which it seems to have done but not totally. So I moved up again to the FG500 with the SFX-2 pad and did a very small section to try and totally remove the swirls but that didn't really do anything additional.
After that the sun hit it again and then I could see some holograms so read a bit more and then did the whole bonnet with the FF3000 on the SFX-3 pad again to help refine the finish and remove them. I think that that may have worked but will only know when its in the sun. Maybe I'm just expecting too much?
After every polish I have wiped down with IPA and I have marked the backing plate up. Looking at 1 to 2 revolutions per second on speed 5 on the Das 6 Pro.
Since then I have also brought home my 200 lumen LED torch from work which will hopefully assist in correction detection!
stealthwolf:
Sounds like you haven't broken down the polish properly. Do you use the zenith method? Once it's broken down properly, it should have a clear oily finish. There shouldn't be any polish residue. You need to keep inspecting with a light source whilst polishing and IPA wipedown in between each step up/step down.
