REPAIR PROCEDURE
a. FILLING
only the material
Material:
Part A - Flexible Resin
Part B - Resin Hardener
Equipment:
Putty Knife
Squeegee
Heat Lamp(s)
#220 & #400 Sandpaper
DA Sander w/#80 Discs
Body File w/Holder
1. Clean the repair area with a wax, grease, and
silicone removing solvent. With a DA sander ad­
justed to a feathering action and fitted with a #80
grit disc, remove the paint film in and surrounding
the area to be filled. This is necessary because the
patching compound will adhere only to the foam base
material.
2. If the surface to be repaired is cut or gouged,
use the DA sander and a clean disc to enlarge the
cut or gouged area(s). This must be done to ensure
removal of grease, oil, or dirt from the area to be
contacted by the repair material. This action should
also taper the edges of the cut to minimize the pos­
sibility of highlighting the repair.
3. Mix the patching compound and hardening agent
at the prescribed proportion (10 to 1). The patching
compound and hardening agent should be mixed until
a uniform color is achieved.
4. F i l l the repair area with the mixed compound
to a height slightly above the surrounding contour.
Work out air bubbles, if present.
NOTE: Thinly spread the remaining mixture on a
clean, hard surface to lengthen pot life. This may
be used later on the cured patch for repair of pin
holes.
5. Place a heat lamp approximately 15 inches from
the patched surface for 15 to 30 minutes, or until
the repair material will not transfer to the touch.
