How does Prusament PETG behave under acetone vapor bath?

Hi, I read that depending on the brand, 3D printed objects could behave differently under acetone vapor bath. Some could even deform. How about Prusament PETG? If the objects are made for functional prototyping that requires rigidity and strength, is it better not to use this method to make the printouts look good?

Is any PETG susceptible to Acetone?

Not that I know of ... if prints from some PETG filaments deform, it may be rather because of additives added to the blend rather than polyethylene itself. ABS and ASA dissolve in acetone, to some small extent PLA gets affected by acetone as well (it does not get vapor smoothed, but degrades in direct contact).
