WARNING

Solvents can burn easily, can give off harmful vapors, and are harmful to skin and clothing. To avoid injury

or death, keep away from open fire and use in well-ventilated area. If solvent gets on skin or clothing, wash

immediately with soap and water.

Clean area with xylene or equivalent solvent. Inspect area closely.

If sound-absorbent liner is present on underside of damaged area, remove panel(s) to provide adequate working

area.

NOTE

If damage extends to joint where part is bonded to another, separate part with heat gun and putty knife before

cutting.

Using saber saw, cut out large, straight-sided panel (8) containing damaged area.

NOTE

If damage is next to, but does not include, headlight reinforcement, remove headlight reinforcement from

replacement section, not from hood.

From scrap hood (16) or new part, cut patch (9) from same area slightly larger than original panel (8). Trim patch

to fit both size and contour of original panel.

Sand patch (9) edges to allow 1/16-1/8 in (2-3 mm) gap (10) around panel (8).

On engine side of hood (11), use router bit on grinder or drill to grind away shallow recess. Grind recess to one-

quarter depth of laminate (12) and 1/2 in (13 mm) outward from all sides (13) of panel (8) area. Grind 1/2 in (13

mm) inward from all sides (13) on engine side of patch (9). Slightly taper outside edge of ground area around panel

and inside edge of ground area on patch.

Using 110-220 grit sandpaper, scuff area at least 1 in (25 mm) out from sides (14) of panel (8) area. Scuff at least 1

in (25 mm) in from sides (15) of patch (9). Scuff thoroughly to give surface to which patch can stick. Completely

sand off any undercoating sprayed on these areas.

Bevel edges of outer sides of both panel (8) and patch (9) to about 45 degrees.

Using 220 or higher grit sandpaper, gently feather back outer painted surfaces about 1/2 in (13 mm) beyond edges

of repair areas of panel (8) and patch (9).

Blow dust away with compressed air and wipe area with clean cloth.
