Experienced paint guys I have a question

i'm going to throw something out...
The paint companies have been in business a long time, water based paints have been around a long time.
Matching colors shouldn't be a problem. Biggest problem is probably our own negative attitude towards it...
Fwiw

I couldn't agree more

Most auto manufactures made the switch to waterborne back in the 90's some even in the late 80's

back then there were issues with it, but its been so well refined in the last 20+ years, there really is nothing to fear with waterborne as long as the painter has experience with it.
