E. Applying The Patch
1. As you apply each piece of wetted mat to the sanded
area, work out the air bubbles with the paintbrush and
your index finger.
IMPORTANT
If air bubbles are not removed they will leave deep voids in the patch
after sanding so that you might have to apply additional fiber glass mat.
2. Place the piece of dry fiber glass cloth over the
patch immediately after the last piece of mat has
been applied.
3. Apply a rubber squeegee over the cloth. Hold the
squeegee at a 95 degree angle and apply it from one
end of the cloth to the other. Let the undamaged area
surrounding the patch serve as a guide for contouring
the patch properly.
NOTE: Besides restoring the approximate original shape to
the area, the squeegee removes the remaining air
bubbles in the patch. Also, the cloth makes squeegeeing
possible. It is impossible to squeegee directly on
wetted mat.
IMPORTANT
Take extreme care to remove as little of the resin as possible from the
patch. If too much resin is removed with the squeegee the patch will be
resin poor: that is, not enough resin will remain in the patch to
combine with the fiber glass.
4. Remove the piece of cloth immediately after the patch
has been properly squeegeed. Removing the cloth reduces
the amount of sanding that has to be done later.
5. Allow the patch to cure before going to Procedure
G.
F. Sanding the Patch
1. When the patch has cured, remove the majority of the
excess fiber glass and restore the original contour to
the area with the power sander and 24 grit sanding disc.
