• If the damage or groove is shallow, heat the entire
surface evenly. Apply heat locally if the bumper is
gouged or torn open.

• Do not allow temperature to exceed 158°F (70°C) or
the bumper will deform
5. Apply filler (BOND QUICK MENDER.)

I to I, and stir until they are thoroughly mixed.
-1 .Apply the mixture over the damaged area with a
putty knife using light pressure.

bumper.

the back, and apply the filler over the outside
surface.
After the filler has been dried, remove the tape
and apply filler to the side that was taped.
NOTE: Apply filler so it extends over more than the
damaged area.

proved, 210 kPa (2.1 kgf/cm

,30 psi) air nozzle.

injury.
• Remove all dust and dirt with a tack cloth.

or safety glasses whenever sanding, cutting or
grinding.
