FINISHES
Gelcoat
The gelcoat used on all exterior and interior surfaces of your Yacht is of the highest qual-
ity material available for marine use . This gelcoat has the best possible color retention, gloss,
and resistance to weathering . However, even the best gelcoat needs some maintenance to
preserve its finish .
• Whenever feasible, the deck and topsides should be rinsed with fresh water .
• Wash the gelcoat surfaces with a mild detergent or car wash solution . Use a sponge or towel on
smooth areas and a soft brush on non-skid surfaces . Be careful not to use abrasive cleaners or
solutions containing chlorine .
• At least once a year, apply a good coat of high-quality wax to all smooth surfaces . Buff down
with a clean towel .
If the surface becomes dull, it can often be returned to a high gloss by hand buffing with
an automotive buffing compound of a very fine grade . If a power buffer is used, extreme care
must be exercised to prevent burning through the gelcoat surface . This is particularly true of
corners and edges . Always apply a coat of wax after compounding . Small scratches or abra-
sions, which do not go through the gelcoat, can be removed by wet sanding with 320 grit
paper, followed by wet sanding with 600 grit, compounding, and waxing . For deep scratches
or holes, you should rely on your dealer or local gelcoat repairman to provide a good cosmetic
repair .
Gel coated surfaces can be painted . However, to assure a good finish, which will last, care-
ful preparation and application is necessary . This should be done by professionals .
Teak
The interior and exterior woodwork on your Yacht is primarily teak . This unique wood will
not rot and requires minimum maintenance . All the teak was treated at the factory with a
high-grade teak oil .
On the interior, you should apply a new coat of oil at the beginning of each season . Use
good grade teak oil, which is available through your dealer or local marine hardware store .
This will maintain the rich brown color of the wood .
The exterior teak, if left untreated, will turn a light gray, which some yachtsmen prefer .
However, as the teak weathers, the grain raises, and there is a tendency for the wood to check
and/or split . Periodic cleaning with a teak cleaner will remove the gray color with a minimum
of labor . A good coat of teak oil will help prevent the checking and splitting .
Teak may be varnished, which will produce a beautiful finish and provide good protection .
A varnished interior would normally last two seasons . However, on exterior teak, a new coat
should be applied every four months . Before applying varnish, be sure the surface is dry, sand
thoroughly, and wipe with acetone to remove some of the oil .
Before attempting to varnish teak, you should consult your local marine paint expert .
