The M998 hood and engine access cover are made of fiberglass ( sheet molding compound). Cracks, splits, or
holes may be repaired with a glass reinforced plastic laminate repair kit, MIL-R-19907c, NSN 2090-00-372-
Hood surface has a thin layer of gel coat that may appear
cracked in a " piderweb" like pattern due to hood flexing. No
repair is required.
Examine cracks to determine if they are surface only, or are deep brakes into material thickness.
If filler material chips off at bonding flanges, appearing as cracked but not broken through, area need
not be repaired.
If a total penetration crack greater than one inch exists in critical areas: hinges (3), latches (2), or hood
stop (1) areas, repair immediately.
If total penetration cracks exist in non-critical areas, do not repair until size is greater than three inches.
If severe breaks develop in one area, remove fragmented material and use repair procedure for holes.
