The Test

The "BEFORE" Sample of fiberglass after 10 months of continuous underwater exposure
in the Florida Keys. The sample was not removed or cleaned during the full 10 months.

Final piece of fiberglass sample after rinsing and light scrubbing. The barnacles shown in the above
picture popped off and are shown in the picture below. After 10 months underwater with no cleaning
you can see the effectiveness Crystal Marine Pro will have in protecting your hull from the
damaging marine growth environment.
