All removable structure shall be installed at the faying surfaces with which type of sealant?

Sealing removable joints requires a material that protects the joint from moisture and corrosion during service but can be cleanly removed when the structure is taken apart. Class B sealants are designed for this purpose: they provide an effective seal in operation and are formulated to be removed without damaging the faying surfaces or leaving hard residue, making maintenance and reassembly straightforward. Other sealant classes are typically intended for more permanent joints or different service conditions, which can make removal difficult and increase the risk of surface damage or corrosion upon reassembly.
