REPAIR
1. General
Common repair procedures for seating products typically involve replacement of high-wear, aesthetic components, such as armcaps, cushion covers, and shrouds. Removal and installation of many of these parts may be accomplished using DISASSEMBLY (Page Block 3000) and ASSEMBLY (Page Block 7000) or by referring to the figures in the Illustrated Parts List.
This section describes tasks that may require an additional amount of procedural information.

2. Procedures
A. Repairing Damaged Surfaces
(1)
Minor surface damage (Light alloy and steel components)
(a)
Blend out minor surface damage using an abrasive cloth. NOTE: Minor surface damage is considered to be abrasions and scratches.
(b)
If applicable, restore the surface treatment in accordance with local regulations.
(2)
Minor surface damage (Thermoformed plastic panels)
(a)
Clean plastic surface with alcohol or an alphatic solvent such as mineral spirits, heptane, or hexane.
(b)
Fill any surface irregularities with catalyzed polyester resin filler.
NOTE: Catalyze only the amount of filler that will be used immediately because the material will begin to harden within five minutes. An automotive body repair surfacing putty may be used as a fill material.

(c)
Level with spatula before filler hardens and restore texture by stippling with a stiff-bristle brush.
(d)
After filler has fully hardened (10 to 15 minutes), rub the area lightly with an abrasive cloth to blend repair into adjacent areas.
(3)
Screw threads
(a)
Slightly rough or burred threads may be cleaned up using a thread file or small three-corner file on external threads and a plug tap of correct size for internal threads.
