Why do I keep instilling tiny chip marks when detailing?

I noticed an issue in my past 3 details (2 of them were family cars). It seems as though I somehow make tiny chip marks into the paint. The locations of them vary, 1-2 on the hood, on the the quarter panel, etc. Usually it's like 4-5. I can't figure out why I do so. I keep my pads clean and don't use them if I drop them on the ground. I use a Makita rotary and LC wool and foam pads.

I.e. I was doing a pass on an Altima last week with my wool pad and noticed a chip that wasn't there on previous passes.



Please help:think:
 
Polishing can't possibly create chip marks... A rotary works by spinning, so the worse you'd be doing is creating severe rotary holograms or swirls, not chipping the paint. How big are these chips? Like stone chips?



Unless the clearcoat was cracking or something, there's no way your rotary polishing will produce paint chipping.
 
Possible that there was some small pre-existing damage in these spots (i.e. - stone chips) and passing over them with the buffer just pulled a little more paint away.



I've also seen something like this when detailing cars that customers have used "filler" type waxes on before... the chips are barely noticeable before I start, but then all of a sudden, mid detail, I can see them clear as day.
 
No way I can imagine the rotary actually causing that type of damage either, so I agree with Dylan06SS. When I rotaried my (very used) M3 I suddenly saw a *lot* of pitting that I never noticed before. I suspect that whatever the seller had applied concealed this damage and I merely uncovered it through my aggressive rotary work. Areas that would be *very* hard to chip didn't have it, areas that are subject to stone chips and "normal damage" did have it.
 
whoo thanks guys. It has seemed to happened before with both foam and wool pads. I'm still a little concerned and will be sure to do a much better pre-cpompounding/polishing inspection.

+1, I always notice a few dings/chips after polishing, due to the removal of all other imperfections, so they become more noticeable.

Also they can collect some polish to make them stand out.

Exactly what I was going to say. Once a little polish gets in the edges of the chip and dries to a lighter color it highlights the chips a LOT.
