well i got to use the towels today, i was no impressed.
The blue towel, which is the "polishing towel" used for buffing was liek a peice of paper, it was hard and thin, almost like they had compacted it. It did not hurt the paint but it also had no knap so it would not pic of the duragloss that was on the paint, I needed to use the quick detailer to do this. In the end it just lead to a wep mf cloth.
as for the yellow, or cleaning towel, it was a little softer, has some knap but I was still not impressed, to me it seemed like a cheap mf. I ended up using it on the glass, which worked well. i liked it there, but I would not recomend buying them
They are each over 10 bucks, IMO they are not worth that much, sorry carlos, there not special
