8.2 REPAIR USING FIBERGLASS PASTE
Fiberglass paste is used for repairing small
dents, scratches, and pits. Paste is made by
mixing resin, hardener and fiberglass strand or
filler to the consistency of putty. Where it may be
necessary, sand paint away around damaged
area. On underside of coach, scrape away
undercoating from damaged area, and wipe
clean with solvent.
Preheat the area to be repaired using heat
lamps. Mix desired quantities of resin and
hardener according to manufacturer's
instructions. Add powdered fiberglass strand into
mixture to thicken it into a putty state.
NOTE
If repair is made on a vertical surface, adding
powdered filler material to mixture will reduce
the tendency of hot resin to flow or run.
Apply the material with a putty knife or similar
object, building material up to the desired
contour. For deep filling and on vertical surfaces,
several layers of material may be used.
A hacksaw blade, held flat to adjacent contour
and then moved in a sawing action across the
repair when the resin is in a gel state, will
remove excess resin from repair. Finish repair
with the same procedure as when using
fiberglass cloth.
8.3 TYPICAL FIBERGLASS REPAIR
PROCEDURE
Remove all loose particles or damaged material
using a power sander or rasp. Clean area,
overlapping hole approximately 1" to 1-½" (25-40
mm) all around. Remove all dirt, grease and
paint from area to ensure good bonding surface.
Feather the cleaned area all around (Figure 2).
FIGURE 2: FIBERGLASS REPAIR 18089
Cut a piece of fiberglass mat slightly larger than
area being repaired. Impregnate mat with
general purpose polyester resin catalyzed
normally. Use a clean paint brush to apply the
polyester resin. Apply impregnated mat over hole
and press onto surface with brush to obtain good
adherence. Another coat of general purpose
polyester resin can be applied at this time
(Figure 3).
FIGURE 3: FIBERGLASS REPAIR 18090
NOTE
Remove all air between surfaces being joined.
Allow area to harden and sand surface to
remove any wax.
Apply another mat, followed by a cloth patch,
and another mat. All layers must be thoroughly
impregnated with polyester resin, brushed well
and free of air. Apply more layers of mat and
cloth as required until the desired strength and
thickness is obtained, minimum two 1-½ oz
(43 g) mats and one 9 oz (255 g) cloth (Figure
4).
