To each their own, but I would just point out there are people who've used wax for years and never had problems.
Wax expands and contracts with heat too. As does just about any solid or liquid known to man. And wax would have to have one heck of a strong bond to actually hold together under expanding paint and crack it. You'd mentioned once about "breathing". Rather than argue that, I'd point out that an acrylic product like Liquid Glass, or a polymer like Zaino, would also inhibit this "breathing" as they seal the paint.
The whole point of a protective product
is to seal the paint. If the paint is protected from oxygen in the air, it will have a much harder time oxidizing. And waxes or sealants help keep environmental contaminents off the paint, at least for a short time until you remove the contaminent. Some also help to reduce the UV that hits the paint.
I would ask what evidence you found that the peelign paint, crows feet, etc were caused by wax, though? How do you know the crows feet weren't from too thick a film of paint, too little flex agent, a body panel that flexs too much, etc? Or the peeling from improper prep? How can you look at failed 10 year old paint and conclusively say what caused it to fail?
You are certainly entitled to your opinion, but there are plenty of people (more than 5% of "old timers") who have used waxes for years with no problems. Considering there are several big companies that have made wax products for over 50 years, I'd guess that they'd be out of business if 95% of the detailing population from 1960 and beyond feels they will ruin paint.__________________
