Q's after first time PC usage

I've looked through the dozen (hundreds?) of threads on this and haven't found the exact answers I was looking for. A couple of questions after trying my PC for the first time...



A) I was using a yellow pad + 3M Perfect-it SMR (39109) and following the instructions from Roadyfly. Sometimes I was getting it to break down to a powder, sometimes I could only get it to a haze. Was I using too much product, too little pressure? I noticed that the panels I did that were in the sun tended to break down better than those in shade, if that helps any! Some areas I worked and worked and could never get it past the 'haze' (which would buff right off with a MF). I'm not sure I was getting the full use of the product (from how I understand it works).



B) I removed the majority of the swirls, but still had some small ones (more visible after washing prior to Z application). Do I need to go to something more aggressive (I also have 3M Finesse-it II Machine Polish / #39003), and from what I understand, this is slightly more aggressive?



C) I am pretty sure the SMR contails oils & fillers, so I did do a Dawn wash prior to the Z, if I step up to the 39003, do I still need a wash prior to Z application (I believe I have read it does not contain fillers)?



I was pleased with my first efforts with the PC, but now want to refine them with the help of those who know, so your suggestions would be greatly appreciated!
 
kompressornsc- I'm not a fan of 3M's SMR, but I'll try to answer your Qs.



a) Yeah, you probably used too much. The spots in the sun worked better because the heat helped dry it out faster.



b) Yeah, use something more aggressive and save youself some work/aggravation by using something without fillers. *I* like the newer 3M PI-III stuff better. Get the RC, (05933) and MG (05937). They work well together, by hand and PC. I haven't used FI-II for a few years and I wasn't too thrilled with it then.



c) If you're gonna try a new product, use the PI-III stuff (IMO, of course). I can't remember if the FI-II has fillers/oils or not, but I sorta think NOT. Still, you often have to follow up the FI-II with something milder anyhow.
