6.12 Paint adhesion. Coated parts should be allowed to dry in accordance with the chemical manufacturer’s recommendation before they are subsequently painted or adhesion failures may occur. When coated parts are stored for extensive periods before painting, they should be cleaned in accordance with 3.2 to reactivate the surface by removing dust particles. Excessively thick coatings may result in paint adhesion problems, such as blistering, due to higher amounts of soluble material under the paint.
