I'll share what I've heard commented upon, as well as my first time experience with using CQuartz UK.
Corey at Carpro, and I believe some of the other pros have said to use the MF Suede Towels to level-smooth CQuartz after application, but I get the strong impression that this is not absolutely set in stone.
As for applying CQuartz, I would say a big definite yes to using the MF Suede, with the Foam Applicator Block. That even many of those applying other brands of Coatings still like the Carpro tools the best.
Now all I did, was I came behind application with a brand new Carpro Orange Boa MF Towel, and these are very plush, and very soft.
After I applied UK, it looked so darn good after a cross hatch application that it looked like I really didn't need to do anything after. All panels looked like smooth glass, no streaks, high spots, or any areas that hadn't flashed.
Like the product went down like I had just sprayed a coat of clear coat onto the paint finish. I did like I say come behind with the Boa Towel, just to not tamper-monkey with tested and proven methods-directions used by others.
Now whether there was some downside to using such a plush MF to do the final wipe, I honestly cannot say? I don't believe such a towel then came along and just considerably removed the precious film coat layer I just put down?
Waited a full hour, then applied Carpro Reload v2013 with another brand new Boa MF and all went perfectly well with that also.
3-4 hours later, after all was done, I washed all MF towels from all the polishing processes, Eraser wipe downs, and the UK and Reload Applications. Those two Boa Towels IMO were just as soft, and luxurious as before I used them. No harm done to them evidently.
