FREQUENT AND CONTINUED USE OF AbRASIVE POLISHING COMPOUNDS, EVENTUALLY ERODES THE GELCOAT.
FIbERGLASS SURFACES
(Continued)
Gelcoat eventually dulls with age, much like the paint on a car . Restore the gelcoat’s luster using an electric buffer and a very fine
grade polishing compound . Ask your Marquis Dealer what brand and grade of polish to use .
Gelcoat stress cracks are common on all fiberglass yachts . The majority of stress cracks are cosmetic and limited to the gelcoat
surface only . Gelcoat stress cracks are rarely an indication of structural problems . Contact your Marquis dealer if stress cracks are
found .
NOTE: The repair of cosmetic (non-structural) gelcoat stress cracks is not included under the terms of the Marquis
Limited Warranty .
GELCOAT REPAIR
Minor gelcoat nicks and cosmetic scratches are not difficult to repair, nor do either require the use of special or unique tools . Visually
satisfying repairs takes little effort . Repairs to fiberglass laminates or structural fiberglass components are best left to the experienced
technicians at your Marquis Dealer .
A gelcoat repair kit is available from your Marquis Dealer (Marquis part number
82036-03
) . The kit includes: color matched gel, gel
hardener, and detailed instructions on making gelcoat repairs .
GELCOAT bLISTERS
Fiberglass is a durable and economical material, however; it is not indestructible . Blistering is the most problem associated with fiber-
glass . The blisters generally form in the gelcoat or in the outer most layer of laminate . The blisters can range in size from microscopic
to two inches or larger in diameter .
The fiberglass blister’s appearance does not indicate structural problems or faulty hull lamination . Gelcoat blisters form resulting from
a natural process, and are quite common . Contact your Marquis Dealer if blisters are discovered on the underwater portion of the hull .
HULL bOTTOM
The underwater portion of the hull is coated with a high-quality, factory-applied coat of anti-fouling bottom paint . The paint is applied
after the hull has been carefully prepared . The paint has a high copper content and anti-fouling elements that retard the growth of
marine life on the bottom of the hull . The anti-fouling elements in the paint have a limited life span, usually from one to three years,
depending on how and where the yacht is used .
Inspect the hull bottom once a year . Repaint the hull if gelcoat is showing through the bottom paint . Use a paint that is compatible with the
factory-applied paint . Failure to do so can void the bottom paint warranty . Also make sure the paint is formulated for the type of water the
yacht is operated in . See your Marquis Dealer for assistance in selecting an appropriate bottom paint .
To prepare the hull bottom for painting:
Lightly sand the existing paint with 80 grit to 100 grit sandpaper . 1 .
Remove all dirt and sanding residue from the hull . 2 .
Apply the new paint using a sprayer . Using a sprayer applies the smoothest coating and the best hull efficiency . 3 .
Allow the first coat to dry before proceeding if a second coat will be applied . 4 .
UNDERWATER METAL COMPONENTS
The hull’s underwater portion has been carefully prepared, primed, and coated with a high-quality, anti-fouling bottom paint at the
factory . However, the underwater metal components, including the shafts, struts, propellers, trim tabs and thru-hull fittings, were NOT
primed or painted at the factory .
