6. MAINTENANCE TtPS:
Get in the habit of checking fittings for cracks, wear or fatigue. Particularly, check locknuts which
often seem to come loose.
6-1. FIBERGLASS SURFACES:
Maintenance of today's fiberglass sailboats is extremely simple when compared wtth the upkeep
necessary to keep boats of other materials in "Shipshape and Bristol Fashion".
The glossy outer surface of your laminated fiberglass boat is known as "gelcoat", a polyester resin
into which coloring pigments have
been
Incorporated.
It should be hosed with fresh water after every outing. At least once a year the smooth gelcoat sur-
face should be waxed and pollished with a good automotive wax or a boat wax. A power buffer will
make work on the large areas
~ike
the hutl easier, but care must
be
taken not to cut through the
gelcoat surface, particuiarfy at corners and edges. For power cleaning use a LIGHT abrasive
cleaner. while a heavier rubbing compound may be used when
polishfng by
hand.
After buffing, wax and polish all surfaces except the non-skid areas.
NOTE:
GELCOAT:
A can of getcoat is enclosed with your boat for touch up.
tt
is of ISO type and does not include
catalyst, promoter of paraffin wax.
At 25 degrees Celsius temperature:
1) Add the promoter- 0.5% by weight and mix throughly.
2)
Make a 2% paraffin wax solution in stylene and add this solution 4% by weight to the gelcoat
and mix throughly and
3) Add the catalyst- 1% by weight and mix throughly.
YAMAHA uses:
Promoter:
Cobalt nafthenate, 8% solution in toluen.
Catalyst
Methyllsobuthyl keton peroxide, 75% solution
in
Dl-methyl phthalate or
Methyl ethyl keton peroxide, 55% solution in
Di-methyl phthalate.
SAFETY PRECAUTIONS:
1.
ALLOW AMPLE VENTILATION.
2.
KEEP AWAY FROM OPEN FLAMES AND SPARKS.
3.
NEVER MtX JUST PROMOTER AND CATALYST TOGETHER-A VJOLENT EXPLOSION
WILL RESULT.
