One thing about this business is it changes overnight and I'm out of the loop the last few years with the OEMS.
Wiht pricing as critical as it is today for a business to survive it would never shock me what may start showing up on the cars themselves or replacement parts.
Most critical is the OEM replacement parts stay with the same coatings, minor problems were sprung on body shops when they started to change to waterborne instead of solvent as it is hard to tell the difference and some of the higher end shops had adhesion problems until the word got out that they were not dealing with the same coating as before.
A lot had to do with the system they were using and the process, so a slight change and process, took care of the problem.
Now there seems to be a rash of calls with some OEM parts lifting, no matter what you put over them, especially on new coated bumper.
So who knows what they are using on all the parts.
