Micromarring and the PC

I don't often run into a lot of micromarring problems when using the PC, but when I do I have a lot of trouble getting them out. By micromarring I mean the pattern of repeated small dots sometimes left behind after compounding (rather than small scratches or blemishes from washing). A few questions:



1. Do you get more micromarring (with the PC) on harder or softer paints?



2. Does a rotary cause micromarring as well?



3. I've read post that state to use a compound and a polishing pad to remove them, but I've also read that switching to a finishing pad and an ultra fine polish works well. I'm confused.



4. I've also read that Meguiar's doesn't reccomend using a cutting pad with the PC/G100 because it may cause severe micromarring that cannot be removed? Is this true?



Thanks for any help guys.
 
1. Softer paints.



2. Yes, it can.



3. You remove marring with a less aggressive polish/ pad. Say you just used PB SSR2.5 and a orange pad. Then youll want to go over that with SSR1 and a white pad. If you use SIP with a white pad, then go over that with 106 and a blue pad.



4. I dont know about that.
 
My $0.02 follows:



1. Only on very soft paints (if I'm using the right pad/product combo to begin with).



2. Not the same kind of micromarring, but the rotary can/will/does instill holgrams unless you're a real rotary-meister and those are even worse than the micromarring IMO.



3. Depends what kind of micromarring they are. I've done OK using a finer/milder combo as the micromarring *I* got was from the initial bite of the product.



4. IMO that's just a CYA thing they do so people don't [mess] up and blame them. Plenty of people have used the 7006/burgundy/cutting pads via PC with no problems at all. But of course you gotta be a little careful with any aggressive approach and yeah, it *is* possible to instill (new) marring that you won't be able to get out (at least without switching to a 4" pad setup).



FWIW, for major/significant correction via PC I just use 4" pads instead of larger cutting pads. Much, much better IME.
 
Just my experience here...



It all depends upon how soft the paint is and to what level it is has been polished. If you use a rotary and take a softer paint to a very high level of finish, then using the PC even with a finishing polish *can* micrmar the paint. For me, I find that using a pad that is too soft will micromar the finish, even with the perfect finishing polish. If I am polishing soft clear I have zero issues finishing with Menzerna PO106FF and a white low-profile 5.5" lake country pad. If I were to try and finish the same paint with a blue pad, it will micromar. I get micromarring finishing with the PC with just about every finishing polish on the market--excluding FPII and po106ff obviously.
 
ebpcivicsi- Interesting point about the too-soft pads. The white Cyclo finishing pads aren't really all that soft, more like light polishing pads. I never use "finishing" pads to polish by PC so the too-soft pad issue never even occurred to me.

Funny you should post this. I've used a Megs tan finishing pad with ZAIO and FP2 on a PC and didn't seem to get as good of results as the Megs yellow polishing pad.

Would that be a case of the PC not generating enough heat to break down the polish with such a soft pad?

That is what I would suspect. Either heat or friction might be missing with a softer pad and a polish, even a light one, with some cut.



FWIW, the burgandy Meguiars pad is great via UDM on harder paints. Could be the higher OPMs and rotation beyond pressures that bog down the PC help it work well.
