Identification should include

blistering (i.e., trapped air raising the paint surface)
dry spray appearance
presence of fish-eyes (i.e., crater-like openings) in the finish
lifting
clouding (i.e., mottling and streaking in metallic finishes)
orange peel
overspray
solvent popping in a freshly painted surface
sags and runs in a paint surface
sanding marks or sand-scratch swelling
contour mapping or edge mapping while the finish is drying
color difference (i.e., off-shade)
tape tracking
low-gloss condition
poor adhesion
paint cracking (e.g., shrinking, splitting, crow’s feet or line-checking, micro-checking)
corrosion
dirt or dust in the paint surface
water spotting
finish damage caused by bird droppings, tree sap, and other natural causes
finish damage caused by airborne contaminants (i.e., acids, soot, rail dust, and other industry-related causes)
die-back conditions (i.e., dulling of the paint film, showing haziness)
chalking (i.e., oxidation)
bleed-through (i.e., staining)
pinholing
buffing-related imperfections (e.g., swirl marks, wheel burns)
pigment flotation (i.e., color change through film buildup).
