How does Gatorshield compare with the competition in terms of rust and corrosion protection?
OD and ID corrosion resistance is monitored on an ongoing basis using salt spray testing. Random samples are prepared and exposed to 5% salt fog at 95F. These samples are examined at regular intervals until a pre-determined end point is reached. Typical end points are the first signs of white rust and first signs of red rust.
