Bad marring after polishing, PLEASE HELP

So a few months ago I purchased the new GG DA. I have done four cars including my own using all the same variables/products and the last two (04 CTS Black and today a Midnight Blue Pearl 05 GTO), I have been introduced to the same problem. Both cars had light scratches/swirls/dry marks and I chose to use m205 with an orange LC 5.5" flat pad. I used onr quick detail with multiple TARGET VROOM towels to remove the residue after buffing. The reason i'm putting the towel type in caps is because I strongly believe this is the problem. Anyway, after polishin and pulling the car outside into the bright sun, I noticed marring on the entire car that appeared to go in the directions of the pattern I used to wipe away the 205 residue. I swear I saw my 3 or 4 finger marks in the marring going in the same direction in a few places. My question is what do you guys think could have caused this and what can I do to prevent this is the future.. cause it really sucks after your polishin and see this on the car (not funny). Any help is greatly appreciated, thanks in advance guys



Update: Few video clips I took today so you can get a better idea of what i'm referring to; any input is appreciated. We also tried to qd the door and then wipe off with 90% ipa to no avail (they really do look like scratches:nixweiss Also, all the towels I used have passed the CD test.

first off do the cd swipe test. If you can wipe a cd with those towels and not have any visible marring then the towel may not be the issue. Some vehicles just marr very easy so you need to be careful. If the 205 dried on the paint from being over worked and you went to wipe it off and apply to much pressure that could have also caused visible marring.



Make sure you remember to wipe down the panel you polished with:



50/50 mix of alcohol and water to assure there are no fillers and that the panel is surely corrected.
 
If you're working the 205 right, there should be little to no residue left. I've used the VROOM towels before, and while they are not the best towels I own, they do a fairly good job. I always fold them into quarters, so there is a little padding between my hand and the paint.



And as vtec mentioned, you shouldn't need to apply a lot of pressure to get the residue off. If you do, that's a sign that something is wrong.
 
black GM paint mars super easy, so I could see you having and issue there. Are you sure that it isn’t just polishing residue? I know that m205 smears a lot sometimes and is difficult to completely wipe away without the help of a 50/50 mix of alcohol and water.
 
Some sorta-random thoughts follow:



-GM black is soft? Clear is clear (odd BMW-type situations notwithstanding, is this one of those?) and all the GM clear I've worked on was somewhat hard.



-M205 on an orange pad might benefit from a follow up with a milder pad. While some people like the M205/orange, I'm not one of them, generally preferring a harsher product/milder pad type combo.



-M205 can leave a *LOT* of oils on/in the paint, and getting them off/out can be a huge PIA. I do better with TOL's PrepWash than I do with IPA.



-I'm a big proponent of test-spots; I'd get an approach all dialed-in, working just a small area right to the point where it's ready-to-wax, before doing the whole vehicle.



-And yeah, anything that touches your paint shoud be CD-tested IMO, and remember to test it like you use it.
 
The clear on my black '05 CTS is horribly soft. You can't touch it with your finger without causing swirls, unless both the paint and your hand are super clean.
 
instead of wiping the panel down dry, use some QD and see if you get the issue. I have not had a problem with the Vroom towels at all. Also as mentioned, if you are using 205 correctly, there should not be much residue left at all.

Huh, interesting, thanks for schooling me. Wonder what's with the stupid-soft clearcoats that're cropping up these days :think:

As I said in my original post, I was using ONR QD mix to wipe off the residue.

Try using less polish, could be it isn't marring but simply smearing from trying to wipe off too much polish.

Hmm, I was using the usual method of priming the pad and then 3 dots of polish on the pad. How would I know if I was in fact over do-ing it?



I do not think it's leftover residue because I wiped the entire car with a 50/50 ipa mix and then gave it a generous Dawn wash.



Could it be that I let the polish dry too much on the panel before wiping it off and thus causing the dried abrasives in the polish to scratch the paint as I applied pressure on the mf in removing the 205?



Thanks everyone for their input. I should be attempting to fix the problem in the next few days. Maybe I will even take a quick video in the sun of exactly the marks I'm referring to as to maybe give some of you a better idea. This has really got me stumped
 
Time2Shine- IME this problem, when related to M105, is often/usually a matter of micromarring from the abrasives in the polish residue. When related to M205 it's quite often (actually always, IME) a matter of polishing oils.



Not sure how well the ONR will work when buffing off the M105 residue; it wasn't too great for that when I tried it and I did better with M34.



The oils from M205 can be incredibly tenacious, as in repeated IPA wipes/etc. didn't get them all and I finally settled on using solvents and/or the PrepWash because that was the only way I could get things 100% clean.
