Belzona Facts
This method significantly reduced the installation time and cost for bearing replacement, and extended the lifetime of the component, by eliminating future galvanic, crevice, or general corrosion from this part of the rudder. Four rudders were repaired in less than a week and Belzona is used from new to prevent these problems.
