~One man’s opinion / observations ~
The resin (paint) is porous, as is any ‘sealant’, microscopic dirt, road grime and brake dust will compromise your paints protection system. By constantly adding ‘layers’ you are covering the dirt over.
I had a client with a white Jag (a show car) mostly garage kept, that he drove very occasionally, and had x ‘layers’ of Klasse applied, which he added too at each car show. He wanted to enter it into a concourse and asked me to ‘strip-it and renew the Klasse polymer.
After washing, detailer’s clay (which turned almost jet black) I gave it a Klasse-wash (Schnell-alternate) and then preceded with AIO, I went through dozens of cotton towels, as they were all turning black. Mike Phillips alluded to something similar in a recent article on cars with white paint.
~Hope this helps~
