PRELIMINARY STATEMENT
Prior to use it is necessary to read the Safety Data Sheet for
information about precautionary measures and safety
recommendations. Also, for chemical products exempt from
compulsory labeling, the relevant precautions should always
be observed.

PRETREATMENT
The surface area around the dent, scratch or hole must be
clean, dry and free from oil, grease and loose particles.
In case of rusty surfaces, the rust has to be removed to bare
metal.
The entire repair area should be grinded with 120 grit sand
paper.
It is not necessary to remove the paint around the repair area,
as long as the paint has good adhesion to the surface.
Finally the sanded parts have to be cleaned and pretreated
for the next step with TEROSON VR 120.

APPLICATION
Use the amount of Body Filler according to the required
repair area and mix the mass in a ratio of a golf ball
size (40mL) with a 4 to 5 cm (2 to 3 %) long hardener
stripe of TEROSON UP 190, using a spreader until a
uniform color has been achieved.
After mixing the time to apply the filler is approximately
12 minutes at 20°C.
Apply the filler mixture onto the repair area in a way that
the dent, scratch or hole is sufficiently filled.
Thicker layers should be built up using multiple layers.

temperature.
Accelerated cure, using an infrared heater (surface
temperature max. 60°C) is possible after 10 minutes of
