5) Mask off top side of shim 1/4" inside mounting surface of RSM and mask off a
similar area on the bottom so that these areas remain Alodine only (see Figure
6.18). Prime unmasked areas with epoxy primer per MIL-P-23377 or equivalent.
Paint to match aircraft color if desired.
6) The shim must be bonded to the aircraft skin by removing the paint and prepping
the aircraft surface where the shim and RSM will be mounted. Remove paint ½"
inside the outer footprint of the RSM mounting location. Burnish the aircraft skin
and apply Alodine 1201, do not prime.
7) Sandwich the shim between the aircraft skin and the RSM following the RSM
installation procedure in Section 6.9.7.
8) Apply non corrosive sealant around shim and RSM.
