TM 38-260
(b)  Slushing is most often used to coat the inside surfaces of chambers, tubing, oil coolers, metal
tanks, and other cavities not accessible by other means. For this reason, oils and soft thin film preservatives should be
used. If properly selected, the preservatives do not normally require removal from the item before using. If removal
should be required, the preservatives are easily flushed out.
(c)  Pour a sufficient quantity of the preservative into the interior of the item to cover all surfaces
when the item is rotated. If available, a small pump with a flexible outlet hose may be used to pump the preservative
into the item.
(d)  To prevent the collection of preservative in blind holes and crevices, rotate the item, while
draining off excess preservative.  Take care to prevent spilling the preservative to avoid safety or fire hazards.
Equipment and methods of operation should ensure economy through the reuse of preservative.
(e)  After draining, close all openings of the item to keep out dirt and other foreign material. Plastic
plugs are most satisfactory for sealing openings. Male and female types are available for various kinds of openings.
Never use wooden plugs as closures, since splinters from the wood are difficult to remove, and may clog fuel or oil lines
and cause serious damage.
(4)  Brushing.  Brushing is accomplished by coating the item, or limited surfaces of the item, with a
preservative using a brush. This procedure is used when no other procedure is available or suitable. Brushing is used
extensively where only one part of an assembly requires the coating, such as adjoining hinge fittings, inside surfaces of
bushings, or bare metal surfaces next to fabric or rubber materials that must not be coated with preservative compounds.
(a)  Make sure the item is clean and dry before brushing. Use only clean brushes for applying the
coating. Apply an even and continuous coating. Do not handle items with bare hands or dirty gloves.
(b)  Inspect the item to be sure that areas not readily visible are coated. It may be necessary for more
than one brush application to provide an unbroken, continuous coating.
(5)  Filling or flushing. Filling or flushing is accomplished by completely filling the item(s) with preservative
until all interior surfaces are satisfactorily coated and then by draining the item(s).
(a)  Ensure coverage of all interior surfaces by completely filling item with preservative. Care should
be taken so that entrapped air will not prevent complete coverage of the interior surfaces.
(b)  Drain the preservative and close all openings. If the preservative is not to be drained, leave
enough space for thermal expansion. Close all openings and make sure they are sealed to prevent any leakage. Wipe
up any spilled oil, to avoid possible fire hazards.
