Fiberglass Repair

General Information
The HUMMER hood and engine access cover are made of fi-
berglass (sheet molding compound). Crack, splits, or holes
may be repaired with a glass reinforced plastic laminate repair
kit.
Inspection
NOTE: Hood surface has a thin layer of gel coat that may ap-
pear cracked in a spider web-like pattern due to hood flexing.
No repair is required.
1. Examine cracks to determine if they are on surface only, or
are deep breaks into material thickness.
2. If filler material chips off at bonding flanges, and appears
as cracked but not broken through, the area need not
be repaired.
3. If total penetration crack greater than 1 in. (25.4 mm)
exists in critical areas: hinges, latches, or hood stop areas,
repair immediately (Figure 10-11).
4. If total penetration cracks exist in noncritical areas, do not
repair until size is greater than 3 in. (76 mm).
5. If severe breaks develop in one area, remove fragmented
material and use repair procedure for holes.
