CONTAINER REPAIR - CONTINUED
REPAIR OF FACE/SKIN DAMAGE TO FIBERGLASS REINFORCED PLASTICS (FRP)
MATERIAL - CONTINUED
For repair of minor interior damage, filler paste may be used.
FRP material is used in construction of door assembly and central dividing panel of container. Before
beginning a repair, it is essential to identify type of damage so that the appropriate procedures can be
carried out. To identify type of repair required, three common types of damaged are classified below.
Structural Damage This is the most extensive repair and will require all the tools and materials spec-
ified. The damaged area must be removed and a replacement section inserted.
Surface Damage Includes minor gouging of plywood core.
Cosmetic Repair Minor surface scratches.
Structural damage is best described as a puncture completely through the panel. Generally, a puncture will result in
greater damage to one surface than to the other. To determine full extent of the damage, drill a series of test holes around
puncture visible from both sides to determine overall size of area to be removed. Tap surrounding area to determine if
delamination is present. Mark a rectangle around area to be removed and add about 4 in. (102 mm) for suitable
clearance. Drill a 3/8 in. (9.53 mm) hole in each corner to permit insertion of saw blade.
