performance rating, or nomenclature plates.
5. Primers specified in painting schedules may be omitted on items that are factory primed or
factory finished if acceptable to topcoat manufacturers.
B. Tint each undercoat a lighter shade to facilitate identification of each coat if multiple coats of
same material are to be applied. Tint undercoats to match color of topcoat, but provide sufficient
difference in shade of undercoats to distinguish each separate coat.
C. If undercoats or other conditions show through topcoat, apply additional coats until cured film
has a uniform paint finish, color, and appearance.
