In my opinion, chemical cleaners are more for oxidation and staining and such. They don't tend to do much for swirls and micro-marring. Though, I imagine even mainly chemical cleaners still have some abrasive to help the chemicals work.
More abrasive cleaners will still usually do well on oxidation and staining, but will also address swirling and micro-marring.
Are you trying to remove swirls with your prep? It sounds like it since you initially asked about fillers. If so, you probably won't get any cleaning benefit from a chemical cleaner like AIO after using a 1Z polish. Obviously AIO also puts down some acrylic, but I think you see what I mean.
As far as AIO + SG vs PP + GW, I have no idea. I have found that SG has a decent ability to mask/hide swirling. It tends to look more polished/smooth than super shiny. I haven't seen the Glanz outside on the Regal yet (and only used it one time) but it seems to be really shiny and looked very nice (SG looks very nice too). Glanz was a cinch to apply and remove, though the smell is punchier than even Klasse.
OK, I am out of my league, so let me tell you what I think I know...
In dealing with paint, I think we are dealing with:
1) environmental pollution/dirt, stuff that your regular car wash does not get out and you really can't see it. For that, one would use a chemical type cleaner like AIO or maybe even GEPC
2) Micro-marring/swirls/light scratches. For those cases one would use a mechanical/abrasive cleaner like PP or #82. If it was really bad, one might use UPP or #83.
So, to detail a car, to give it a complete prep (clay is not part of this discussion but, I recognize that it is used for embedded particles) one would want to prep it chemically and mechanically so that the topper will highlight and enhance the paint that lies below.
So, if a car does not have micro-marring/swirls/light scratches (2), then I would not want to use an abrassive product in order to keep as much of my clear coat as possible. I would then use a chemical cleaner to clean that dirt that can't be washed off, can't be seen but, is taking away from the shine.
If the car does have micro-marring/swirls/light scratches then I do need those abrassive products. If I understood Mike correctly, he was saying that I could save a step of not using a chemical cleaner because 1Z products have them in addition to the abrassive products.
I hope this is clear. Does what I am saying make sense or did I miss the mark somewhere?
Thanks Aurora for your consideration.
