From that photo no one on this planet could show you any marks in the paint. Photos of horridly marked surfaces can be taken that show a perfect finish but I'm NOT saying this is the case here. Lacquer is tender I agree but outdated by decades and no longer used in production cars. I have worked on it and frankly I'm glad it's a thing of the past. In my experience diapers and cotton towels do mark the surface with tiny scratches. Perhaps what I used back then were not 100% cotton items which is why they performed poorly. Low quality microfiber towels will do the same which I also learned the hard way some years ago.
You stick with what works for you and I'll stick with what works for me.
You are very likely inexperienced inthe automotive paint restoration and application field- how do I know, that's easy, only if you used a cotton product that had synthetic threads would ever mar a surface and this particular photo was taken with both natural and UV backlighting to demonstrate several items of clarity- which as you concur, cannot see any imperfections.
OEM Laytex from the 80's & 90's is almost a sensitive to surface damage as the acrylic lacquers (which is harder the the non-acrylics).
it boils down to this, DO NOT MAKE STATEMENTS THAT ARE PREDICATED SRTICKY UPON MARKETING HYPE.
Thank you.
