In 1985 ZINGA was applied by brush on the steel structures of the Kalvøya Bridge located in the inner Oslo fjord. Paint gloves were used for the carrying cables.

In April 1995, 10 years after the application,
the Kalvøya Bridge was inspected by the
controlling organism Det Norske Veritas (DNV). On 1 December 1998 the Bærum Kommune, owner of the bridge, wrote this testimonial stating that the DNV found the Kalvøya Bridge in a good condition compared to the DNV inspection in 1985 on the previous coating system that had protected the bridge before refurbishing it with ZINGA.
In 1995 only 5 Kg of ZINGA were necessary for
touch-ups on spots that had been mechanically damaged
