FolkArt glass enamels... adding wet paint onto dried paint
I'm using FolkArt's gloss enamel paints for glass.
I recently came across some information that said the project painting should be completed within 24 hours, and that adding wet paint onto paint that has dried for more than 24 hours will not adhere properly. (this is even before the object is baked.)
As I plan to paint very detailed glass items and projects will certainly take longer than 1 day to paint, I'm concerned about durability.
Has anyone verified that this is actually true?
