Hello All,
I have a little experience with ONE type of
sealant.
Years ago a friend asked me to help with the
replacement of port lights on a friends boat.
We decided, due to the absolute lack of
availability of replacement units, to simply cover
the holes in the hull with Lexan (Polycarbonate?)
panels. The question then became how to seal those
'Lexan' panels to the hull sufficiently to prevent
leaks?
In my reading of "Practical Sailor" I had seen a
review of a product called "Boatlife Life Seal".
By the way this is NOT "Life Caulk" which is
different in it's entirety...
After drilling holes through the hull (REALLY
scared the boat owner) we ran a bead around the
OUTSIDE of the hole 'oval', then pressed the
'Lexan' panel into place, inserted the screws into
Life Seal filled holes, and tightened down the
screws until contact was made all around the
circumference of the opening. After 12 hours we
tightened the screws down, to accomplish the seal.
We did this with 4 different port lights.
To this day (many years later) these port lights
are almost the ONLY items on that boat that are
NOT LEAKING!!!
SO. The point is this. ABOVE the waterline, when
sealing different materials, especially difficult
to adhere to materials, use "BOATLIFE LIFE SEAL".
Again NOT "BOATLIFE LIFE CAULK" as that is an
entirely different product!!!
