Metal parts underwater are subjected to two basic types of corrosion: galvanic corrosion and stray current corrosion. Both can harm your boat, propeller, and motor if not correctly monitored and avoided.
According to Flags Unlimited, the significance of the flag's colors is this: The Blue represents the officer and the courage they find deep inside when faced with insurmountable odds. The Black background was designed as a constant reminder of our fallen brother and sister officers.
The red stripe stands for courage the white stripe stands for purity and the 50 stars stands for 50 states Note that, officially, the colors in the flag do NOT have a spâ¦ecific meaning. Any meaning that people state is one they have given it, and not an official meaning.
