Two examples that stick in my mind:

I've had RM brand b/c that was too soft for Meg's #80 for over three weeks (incredible to see such hazing from the initial bite of that mild product!), but was too *hard* for the same #80 a couple of months later. This was the most dramatic example of the lengthy hardening that I've ever encountered.

On the S8 following its deer-incident repairs, I worked on it on-and-off over the course of four months and was able to carefully observe how the paint hardened. During that time, I had to gradually ramp up the aggressiveness of my products/process as stuff that was easy to correct with the PC after a few weeks required the rotary (and aggressive pads/products) a few months later. This was with Spiess Hecker paint. Its hardness in early spring was completely different from its hardness at the end of summer.
These both sound like a paint hardener issues, where the painter didn't mix his hardener right. Rydawg does tons of work for a shop that uses Spies Hecker and their fresh clear is super hard.

Accumulator - I know you have a relationship with your body shop/painter. Did you ever discuss these softness issues with them?
