Corrosion Inhibiting

MIL-PRF-81733

a. All faying surfaces, seams, and lap joints shall be

protected with MIL-PRF-81733 sealant (or sealant

specified in aircraft specific manual). Apply the sealing

compound to one or both surfaces and squeeze the part

together to ensure the complete coating of the entire

surface. Excess material squeezed out shall be removed

so that a fillet seal remains. The fillet width shall not be

less than

1

⁄

4

inch. Joint areas which could hold water

shall be fillet sealed with MIL-PRF-81733 (or aircraft

specific) sealant (see paragraph 7-8.2). If sealing is

impossible because of mechanical or other factors,

prime both surfaces with two coats of MIL-PRF-23377

or MIL-PRF-85582 in accordance with Appendix A

(Navy) or TM 55-1500-345-23 (Army).

b. Faying surfaces that are to be adhesively bonded

shall be treated and processed as specified by the

approved bonding procedure in the applicable

maintenance manual.
