Scott,
I'm sure you're right that neither Winnie nor other coach builders use lacquer. Auto makers gave up using lacquer in the late seventies.
You brought up an important distinction: touch ups that are sprayed by CDI or others are almost certainly not lacquer, most likely 2 part enamels.
However, touch up paint in bottles has been lacquer for decades because it air dries quickly.
Thank you for alerting me to CDI. I then found the Paint_Code_Manual-Itasca on the web. I'll call CDI and will post what I learn.
P.S. The (blue)paint applied by CDI has held up perfectly to 7 years of Florida sun.
