Graffiti is usually caused by forcing
a hard metal object such as a carbide
probe, screwdriver, spark plug or diamond cutter over the surface
of the glass. The result is a deep, sharp edged, damage which
we refer to as a 'hard scratch'.
Glas Weld - Chicago
Glass have developed a two stage process for the removal
one uses an abrasive flat disc to take away the sharp (hard)
edges of the scratch and turn them into 'soft' scratches that
can be treated
by the G Force polishing system - which causes
the glass to
flow into the void. (see Our System for
roughing process creates a haze on the glass, but because the
abrasive action is flat on the surface, there is a minimal stock
glass and thus minimal distortion.
the area is hazed, it is polished by the G Force over
a larger area
than originally damaged and, as a consequence, the flow of glass
'repairs' both the original scratched area and the area that
has been hazed.
there is minimal distortion, this would not be noticeable when
viewed at normal angles by shoppers (shopfronts) or passengers
