3.3 Protection
Protecting blister
A steel blister must be fitted for protection. The blister shown is
welded to the shell plating and then filled with oil to prevent
corrosion. This method provides excellent protection and
simplifies maintenance.
Corrosion protection
As soon as all installation, welding and grinding has been
performed, the trunk and the surrounding area should be primed
and painted using a quality protective coating.
