TL;DR
Millage, in coating work, is the applied thickness of a paint or sealant film expressed in mils, the figure crews quote when describing how heavily a product was laid down. Hitting the manufacturer's target is what earns the warranty: too thin and the film weathers through early, too thick and it can crack, sag, or skin over uncured.

Hitting the manufacturer's target is what earns the warranty: too thin and the film weathers through early, too thick and it can crack, sag, or skin over uncured. On elastomeric and roof coating jobs, contractors document it with wet-film gauge readings taken as they spray.
