or a solid film lubricant.
(K) Bonding maskant--A temporary coating used to protect
selected areas of aerospace parts from strong acid or alkaline solutions
during processing for bonding.
(L) Caulking and smoothing compounds--Semi-solid materials
which are applied by hand application methods and are used to aerodynamically
smooth exterior vehicle surfaces or fill cavities such as bolt hole
accesses. A material shall not be classified as a caulking and smoothing

process that removes permanent coating in small sections at a time,
and maintains a continuous vacuum around the area(s) being depainted
to capture emissions.
(S) Coating operation--Using a spray booth, tank, or
other enclosure or any area (such as a hangar) for applying a single
type of coating (e.g., primer); using the same spray booth for applying
another type of coating (e.g., topcoat) constitutes a separate coating
operation for which compliance determinations are performed separately.
(T) Coating unit--A series of one or more coating applicators
and any associated drying area and/or oven wherein a coating is applied,
dried, and/or cured. A coating unit ends at the point where the coating
is dried or cured, or prior to any subsequent application of a different
coating.
