No one said they are bad quality, but not good enough to be used by a pro detailer. Trust me, I know personally plenty of "detailers" who used these towels. I wouldn't let any of them touch my cars or ever work with me on a detail.
And I can point you to guy that has a minimum $550 fee for ANY paint correction, $295 starting price for interior and he uses WalMart throw away towels (without even washing them first). How they work for him I don't know, but they DO WORK. (For him.) :dunno:
Next time you're working on dark paint with soft clear get a panel to 99% correction and wipe your final polish off with a Costco MF... You will immediately regret it. High quality towels are money well spent when getting into high-end paint correction work.
Like others have said, it will matter less when just doing AIO's or non paint correction wash & wax jobs; however, if a product is known to damage paint - why take the chance?
Playing devils advocate here;
Can't say that they will, not until you know the paint you're working on. Just as you can't say that all this paint is hard an all that paint is soft.
I understand the mindset of not taking a chance, but I also realize that there are a lot of predisposed conditions RE microfiber out there.
Jus' sayin'.... It's all good.

rops:
Costco mf have worked great for me. Yes I have more expensive towels but the Costco mf have never scratched paint that I have noticed. Mine are most likely the old version yellow not gold. I think sometimes people get way to obsessive about things like this.
I totally agree. Given proper care, prewashing to soften them up, removing tags, not dragging an edge, etc. etc. etc. The new ones are pretty darned good for pretty much most of anything out there, period. I've been able to use the old ones with fairly good success as well, but they are not near as easy to work with as the new ones, not even close.
I am a pro detailer, don't you think I know what is out there and what is good quality? No matter what you say, black Porsche paint and Costco towels should not be mentioned in the same sentence.
Sorry. Just like your SUV. Why not a Kia? Once you sit in a Porsche, you know. Once you feel these towels, YOU will know.
On the other hand, these towels "should" be in your stash.

And I know exactly what "these towels" are.

I have both edged and edgeless versions of that puppy.

Do I think the edgeless ones are worth the extra money? Not really. I even questioned Ian about it as mine seem to be from totally different mills with one being softer. He said the edgeless ones have gone through an additional wash cycle. But even after washing they are very different to me imho. :dunno:
I personally like his 530's as the most durable towel on the market. And the 600's and 700's are a freaking STEAL (by the case). :dblthumb2:
All that aside; He of course has 360's and 400's and while the 360's are deeper pile, and a bit more 'flexible' than the Kirkland golds (while being the same weight) they are twice as much and for a basic same spec towel (different backing IE longer pile however) I cannot justify the cost. Now for a heavier towel, then YES.
I'm very interested however in the new "shaggy dog" and waiting on bulk pricing on those puppies. I'm willing to bet they'll replace quite a bit of towels in the less than 700 gsm range!

(Come to think of it, most everything is a steal by the case, just that the ones in your photo cost darned near as much as the new Rupes "kit".)
