When you left the game for a while did you leave residual alcohol on the PF? As you probably know if you have been following Vids guide, alcohol eats through clear or any other type of finish. If left on long enough without being wiped off with a damp cloth I could see it eating through the finish and then through the actual paint.
I have loss paint during this process before but it was do to the paint being chipped and cracking so when the mylar was being pulled up there was more holding onto the glue beneath the mylar then on the PF itself and thus it pulled up. In your case this does not appear to be the problem.
My opinion is that any loose materials if not removed before clearing will only make a mess and or blow off when you attempt to clear. So the removal of the flaking is necessary. Others can chime in on this statement.
Here's what I would do:
- Remove the rest of the glue paying attention to how long the alcohol is sitting (less time the better)
- Wipe PF with damp cloth, then naptha to remove any remaining alcohol and flour
- Remove any flaking of paint and or finish
- Air brush in your touch ups
- Clear
Thanks
