pig tail scratches in clear after intermediate buff

can some one please help, im cutting and buffing a new paint job that i did and im having problems with pig tail scratches in the clear.
the run down
the car was cleared 5 coats, sanded 1500, 2000, 3000. i started with a wool pad and 3m perfect it cutting compound, got great beautiful results i almost didnt want to go to the next stage. which is the perfect it number 3 final swirl mark remover with a black waffle pad, i applied the product spread it around and start to buff i dont see any implication that there would be these little pig tails like from a da. so i drop my speed and repeat the process to see that they got worse. can any one tell me what im doing wrong, the pads are new the product was shook up well and new.
im not completly finished cutting the entire car yet so im going to work on that, then wash the car and dry then try to do the swirl remover again. im washing and drying because im noticeing that im haveing some spots after cutting that theres some dryed on compound it wipes off really hard its not burnt if you take your nail and lightly move it across the area it comes off really easy but a damp rag doesnt take it off. please correct me but i think i need to clean my pad more offton i started doing that and im not haveing that problem as much. please give me a clue here peeps.
thanks

The white waffle pad is for cutting compounds ,The black pad is for polishing. The residue is normal but thepig tail scratches are usually from machine sanding clear instead of wet sanding or possibly an orbital buffer...

I prefer to hand wet sand with 1500 and keep the panel flooded, you can hear and feel as you knock grit/dirt loose and it starts to scratch. That's the problem I ran into with DA sanding. Once the first cut is over and all the surface impurities are removed, you can tackle it with the DA and machine color sand. Just do it one panel at a time and dry the surface after each pass with the DA. I learned the hard way.
As for the residue, keep a couple of each pad if possible and keep them clean. Don't run the buffer extremely fast either. Generally when I see deposits it's from running the buffer too fast and/or using a pad that is dirtied up too much to be effective so I go clean it and then spin it on the buffer at high speed to clear any water. Cleaning the pads in warm water as soon as you're done makes clean up of the pads quicker and lets the pads last longer.

Good luck
Chip.

Yep, I have a hard time wrapping my head around the orbital sander for cutting clear. I wet sand with a bucket that is LITERALLY clean enough to drink out of, I keep the panel LITERALLY clean enough to eat off of and treat that clear like it is the delicate princess it is.

A five gallon bucket of clean water, a large sponge and continuously squeezing a light run of water from the sponge as you sand the surface, keeping the crud rinsed away.

Hey Chip,
Those are two great ideas. I dont why I never figured them out.right around half way through a car I always start getting the residue I did figure out it was because the pad was getting loaded up with compound and wet they work great dry so why didnt I ever use two pads? They even come two to a pack but I always cheap out and just the one...I'll be using two from now on.
And knocking down the trash and rough stuff wet sanding by hand first then doing to the finish sanding with the DA thats another one good one I love dry sanding compared to wet sanding but it scares the heck out of me I only dry sand with 600 before adding more clear...thers no doubt that its way faster and easier...

Brian ,
Like you, I treat my clear (not like a princess) but a women, because I believe ALL women should be put on a pedistal...
...It makes it easier to look up thier dress...

LOLOLOLOLOLOL, no really, LOLOLOLOLOLOL

Ok, here is my drift from the topic, I can catch hell for it later. But in all seriousness, before marriage you try to knock them off the pedestal, so you can see the REAL person and remove your rose colored glasses. Then after marriage, that is when you hold them up on the pedestal. Because you have accepted them for what you saw before and EVERYTHING you see had better be only the good stuff.

Dr. Brian

Before I got married I saw "the good stuff" all the time, sometimes two or three times a day....
Now I gotta geter drunk and/or slip her a roofy.... and I never look ,,,it dont look like the same "good stuff " I remember seeing..I completely understand why those middle east guys make the women wear those burkas with only eye holes cut out,what I cant understand is HOW they got them to wear them ...All I did was try to get her to put a bag over her head and she dam near killed me...

in response to the multiple advise post's the whole car was wet sanded with 1500 with a soft dura block, with clean water with a drop of dawn dish soap. the car was kept clean and not a inch was missed. it was then wet sanded with a palm sander with a tight da pattern with a thick soft interface pad with 2000 and 3000 grit, both wet sanded. then washed between every step in sanding when i started the process of buffing the car there was a perfect surface no pig tailing. after i buffed with a wool pad and cutting compound there was no pig tailing. it was after i had started to polish with step 3 3m finees it compound with a new black waffle pad that i got the pig tailing marks.
i had to day re buffed it with compound in that area and changed the black waffle pad and used a little more polish and a spray of water and its now like a mirrior, basicly there was something on the pad. im going to add some pics to show the resaults of the first cut and polish, ill probly polish it again when i get everything assembled and all the weather stripping in. and never mind the ugly guy takeing the pic i needed something to show the reflection, and this is under bad shop lighting. so let me know what yeah think.

in the black pic there looks to be some wrinkling or streaks it is not it is plastic that is stapled across the rafters of the garage look at it close and youll see that it isnt a paint defect or buffing problem.

If it is small orbit pigtailing, I would think it's grit under the DA pad. If it is big swirls, I'd think something on the buffer pad unless you're using a randow orbit buffer, then pigtails from buffing and getting something in the pad are easy to comprehend.

like everybody else I like wetsanding. If I do any da sanding it's trizac 3000 on very low. It takes a lot longer but it turns out waaaay better by hand. I also let the clear air out a bit before I start buffing.
