3.
On  a  piece  of  polyethylene  place  a  piece  of  cloth  cut
larger  than  hole  being  repaired.    Saturate  with  resin
mixture.  Obtain a layer of mat cut larger than the hole
being  repaired  and  position  it  on  the  cloth.    Saturate
mat also with the resin mixture.
4.
Coat  the  inner  surface  of  area  being  repaired  with  the
resin mixture.  When tacky, apply the patch prepared in
item   3.      Using   the   polyethylene   sheet   press   out   air
pockets and allow patch to cure.
5.
On a piece of polyethylene, place another piece of cloth
larger  than  hole  being  repaired.    Saturate  with  resin
mixture.    Apply  two  layers  of  mat  (Fig.  4),  saturating
both  with  the  resin  mixture.    Coat  the  outer  surface  of
area   being   repaired   with   the   resin   mixture.      When
tacky, position the entire patch on the prepared surface
and press into position.  Allow the patch to cure.

6.
After the inner  and  outer  patches  have  cured,  peel  off
the polyethylene and smooth the outer surface.  Any of
the polyethylene material left on patch will be removed
when sanded.
7.
In  the  resulting  low  spots,  apply  plastic  putty.    Then
over the putty place another sheet of polyethylene and
squeeze well to remove all air.  When putty has cured,
remove polyethylene and sand down to a feather edge.
Crack or Split:
1.
Remove  loose  material  and  grind  to  a  broad  "V"  (Fig.
5).  Clean inner panel also.
2.
Align parts.  A nut and bolt with large flat washers may
be used to draw parts together.  See Fig. 6.
3.
Cut one or two pieces of mat and apply
to  inner  surface  with  resin  mixture.  (On  cracks  where
excessive   stresses   may   occur,   apply   two   pieces   of
mat).  Apply  a  piece  of  cloth  with  the  resin  mixture  to
the  inner  surface  also.  Extend  patches  beyond  break
about 2". Press the patches firmly into place and allow
to   cure.      NOTE:   It   is   a   recommended   procedure   to
leave  the  washer  and  nut  (if  used)  in  the  patch  if  the
mat and cloth were applied over them.

4.
 
Mix a fresh supply of plastic putty and apply over the
outside  surface  filling  the  large  "V"  like  valley  (Fig.  5).
Before   the   plastic   putty   cures,   remove   the   bolt   and
washer (if used) from the outside and fill the hole with
putty and allow to cure.

5.
After  the  putty  has  cured,  sand  down  to  the  exposed
surface.
Small Scratches or Chipped Area:
(No damage to basic fiberglass structure)
Remove    paint    from    area    being    repaired    and    fill
damaged area with a plastic putty mixture.  After area
has cured sand smooth.
