i agree 100%

i am a PPG certified painter. been certified since they started the certification in the late 80's. i currently spray water basecoat clearcoat. i started painting PPG basecoat clearcoat since DBU was first introduced in the early to mid 80's.
i have never had a clear coat peel problem in over 30 years.

if you have a peeling problem you did something wrong.
5 biggest errors.
most common mistake is lack of film build on the clearcoat.
second one is spraying the last coat of basecoat on to dry.
trapped solvents.
then contamination of film build.
mixing manufacturers products.
