Tiny pits in the clear coat from PC?

Can anyone tell me why this is happening? I am polishing my mom's black S430 and I have noticed tiny pits appearing on certain passes that I have done. I believe it is either from the buffer movement being too fast or too much pressure. Im using SSR1 & 2.5 with white and orange LC pads, both combinations have caused it I believe. Another interesting thing is that it seems to only happen on the upper part of the door I am polishing, is there any explanation to this? It would be great if there was a way to remove them, but if I can keep it from happening again that is fine as well.
 
Cars never been painted. I have the same problem on my '03 Ram that is also black, it is all over my hood too which is oem paint, and my passenger door which has been repainted. i'll try to get some pics
 
If this is the first time you're polishing them with a pc and good products, could it be you're simply seeing stuff that was always there but not noticeable until you cleaned up the rest? I have a '00 black Honda, and that's my conclusion for the same thing as you describe it. I just figured it was one of the downfalls of a good polishing - seeing so clearly the defects that you never noticed before.
 
On the hood, if you're just noticing it, it's probably some pitting from road debris? When you lay down a really nice polishing job, the stuff that remains seems to be very noticeable compared with the highly polished surface.



I think this may be one of many reasons why silver cars are so popular?

Notice every time someone notices pits in their paint its with 2.5 on dark colors. Very very weird, I stopped using it altogether on dark colors after the same thing happened to me.

I've been having a similar problem on my black/darker colours, can't figure out what the hell is causing it. Been using OC and Menz 106FF, yellow 4 inch LC and blue Edge2k pads respectively via PC.



Does it look something like this?

^Yep, just tiny clear dots....interesting. I read that thread you linked to sludge and saw someone say that the optimum polishes removed the pits, which i need to get on asap because my Ram's hood & passenger door is covered in them. Does anyone know if Menzerna IP or FP II would remove the pits too? I have both of those but wont be able to try them out for a few days

Not sure about the Menzerna, but Optimum did seem to make a difference. The truck was a '91, never polished before, did 2 passes of OC with a yellow LC 4 inch pad and then one pass with Menz 106FF on a blue edge2k to finish and there was very little of these pits.

Weird either way, but I guess optimum does seem to take care of the problem. Another hypothesis I was thinking of for their appearance was that those dots/pits might be where a deeper scratch could have started, and as it went along the clear whatever was causing the scratch observed lighter pressure or some other factor, so when you polish you get the lighter part out but the deeper starting point still remains?
 
The micro marring (piting effect) is a result of high OPM combined with a stiff polish pad. Set your PC on speed setting 4 (roughly 4500 opm) and apply just enough preasure so the foam pad sqeeshes down lightly. Also stay away from moisture, as it can make some polishes very aggresive and leave micro micro marring behind.
