WINGS
1.
Clean the entire frame thoroughly. Blow out all Ribs and Wing Spars to
remove metal shavings.
2.
Scotch-Brite all sheet metal surfaces and clean with Acetone.
3.
Cut out the 2 formed Bolt Covers to lay flat against the Leading Edge Spar
and to cover the 3 FWD Strut Attach Plate Bolts. Glue on Bolt Covers.
4.
Apply anti-chafe tape around sharp edges (masking tape). Refer to
FIGURE 08A-04.
5.
Apply one coat of thinned U-500 to the sheet metal using a soft wide
brush, let dry. The thinned U-500 applied to the metal under surfaces
helps prevent pin-holing in the paint finish. Make sure to remove brush
hairs from the surface if necessary.

7.
Position the Wing top side up on sawhorses or other suitable work

HINT: RANS uses two "A" frame stands with pivots so the Wing
can rotate and be locked in any position.
You may consider purchasing or
building such a device. Contact the factory for information. If you are using
such a stand, it is acceptable to drill a 1/4" diameter hole through the Tip
Bow for a pivot pin.
