Unremovable Swirls/Scratches?

I greatly appreciate the input guys. I did figure out that the defects that I were referring to as holograms where actually micro marring very close together and at a high frequency such as to give a white appearance that flashes sort of like a hologram. In addition there where some deeper scratches surrounding the marks. I am very happy to say that after almost a week of trials, tests, and research last night laying in bed I was thinking and the solution that worked hit me. I was thinking about the paint on this vehicle and I thought it's hard enough to need M105 and an Xtra Cut DA Microfiber disc to remove the defects but not so hard that the M105 finishes down defect free. On the same lines the paint is hard enough also that the M205 on a polishing pad or cutting pad/disc could not remove the marring caused by the M105. So I thought I induce the marring by using the machine on the highest setting of 6 to remove the original defects and put in micro marring and other small scratches while doing so because the high speed and pressure placed on the machine allows the M105 to cut very deep and aggressive which would makes sense. My thoughts where that I know M105 can finish down well enough in order for the M205 to do its job but how am I going to get this to happen in this situation? Then it hit me, YOU IDIOT - SLOW THE MACHINE DOWN! By slowing the machine down my thought process was that the M105 would still cut enough to remove the micro marring but the speed would not be such to induce violent swirly marrings and scratches and once the M105 broke down it would feather off pretty nice. Today I tried it and offer several variations and techniques the following was the winner;

The DA Polisher, DA Microfiber cutting disc (not Xtra cut) , and M105

I did several test areas on the vehicle where I could very easily and distinctly see the defects induced by the M105 that I have not been able to remove using the following process.

Placing 3-4 specs of compound on the disc.
Tapping the disc around on the surface of the vehicle in about a 1' X1' area (I prefer to work smaller areas)
Setting the DA to speed 4 out of 6 and spreading the polish with no pressure and a moderate speed (I do not want to quickly drag the machine around to spread the polish to avoid inducing deeper scratches.)
I made one slow pass with a good amount of pressure on speed setting 4, released a majority of the pressure and made 2-3 moderate passes and then slowed the machine down to 3 released virtually all pressure and made 2-3 moderate passes before stopping the machine.

Once I wiped away the compound a virtually defect free surface was revealed. I gave it an IPA wipe down just to be sure and got incredibly exited! I followed this up with a polishing pad and M205 on speed setting 5 backing down to 4 and the finish was unbelievable.

Please continue to give input and feedback. All of your comments and ideas have really helped me work through this process.
 
Glad you figured out what was happening.

Doesn't have to be microfiber discs that induce micro-marring. Running ANY cutting compound too fast will cause sharp, abrupt, radical direction changes of the orbital motion on the surface. So what you end up with isn't circular orbits as the pad rotates, but very sharp pointed stars all over the surface.


Meguiar's is VERY specific in how they recommend using the DAMF discs, even going as fas as to state what opm to use when doing correction with the cutting disc(s). They also say what speed is optimal for the finishing disc. ;)

The chart calls for 4800 opm for cutting, and 3800 opm for finishing. (With both the Correction Compound D300 and Finishing Wax D301, but you can run just a touch faster finishing with D302, but not much.)_

Of course that just so happens to be just under where speed 4 and speed 3 (respectively) is with the GG6. Of course it'd SEEM LIKE you would need to run faster, but that's not where the pads do their best work. ;)

M105 uses Super Micro Abrasive Technology (SMAT).

It is not designed to "breakdown" like Diminishing Abrasive Technology (DAT).

In fact, in my experience; if worked too long the compound will actually agglomerate into larger particles and can cause increased marring.


Glad you got it figured out
