Fairing Compounds & Fillers







340 FAIR-SO-LIGHT
A Premium Lightweight Marine Fairing Compound
Smooth “Lightweight”-Easy to sand.  A marine grade underwater polyester fairing 
putty.    Its creamy consistency spreads easily and resists sagging.  Minimal paper  
clogging - feather edges beautifully!  Low shrink for ultra smooth surfaces.   Tack-free
in  20 minutes (@75 F) for longer working time.  Use on underwater sections of boats
where a heavier build up is required. Bonds well to wood, metal and fiberglass surfaces.

345 BOND-A-LITE
A Premium Lightweight Glass Reinforced Marine Bonding Compound

340-5G      5 Gallon........$ 129.95

 
PRICES INCLUDE BPO HARDENER
This polyester compound has excellent adhesion for structural bonds to fiberglass laminate, such as bonding rudder
halves or hull-deck joints.  Excellent for auto body repair to reconstruct areas where metal is rusted away or badly
damaged.  An excellent trowel-in-place, syntactic foam core for molded FRP parts. Can be used to replace damaged
core, or bed new balsa, foam or plywood core.  Often used as a castable or formable putty for sculpting and taxidermy
applications. It is easily shaped, carved and filed.  High compressive strength, low shrinkage with excellent non-sagging
characteristics on vertical surfaces.  Can be applied up to 3" thick in a single application!  May be used on wood, metal
and fiberglass surfaces.

395 GLAZING PUTTY



Very smooth putty for filling small sanding scratches and pinholes prior to finish coating.  Smooth filling,
easy spreading.






940 VINYLESTER FAIRING COMPOUND
A smooth lightweight fairing compound that is easy to sand and shape.  940 is ideal for underwater applications.  It has excellent adhesive and compressive strengh as well as better adhesion to aluminum, steel and brass than polyester compounds.

945 VINYLESTER BONDING COMPOUND
An extremely high strength, glass reinforced, syntactic compound used for making strong, stiff bonds where gap filling (up to 1-1/2") may be required.  Similar to 345 Bond-A-Lite’s consistency, 945 uses vinylester resin to create a highly water, chemical & heat  resistant bond. (Call for specific applications).  Can be used as a trowel-in-place core, or for core bedding with balsa, plywood or PVC Foam.  An ideal choice for repairs to high stress areas, such as bonding stringers & bulkheads to the hull laminate, and bonding fiberglass panels together. May be used on wood, metal and fiberglass surfaces.

FOURSEAL PRIMER
Fourseal Primer is a high build polyester coating used extensively ofr refinishing fiberglass parts which require sanding
and fairing work.  It is an excellent finish for plugs & short run molds (1-5 pieces) made of plywood, Masonite etc.





*   High build coating (Up to 40 mils wet with  several

     passes to fill a multitude of imperfections).


*   Sands Easy, 4 hours after spraying @ 77º F.


*   Does not load the sandpaper when sanding.


*   Can be buffed to a semi-gloss if a quick plug

    pattern is needed. Follow normal wax procedures as 

    you would with a new mold.


*   Good adhesion with existing polyester molds when

    procedures are followed from the application guide.















Fourseal Primer should be applied in 1-3 mil passes to a film thickness of 18-22 mils.
Make sure spray equipment air pressure is properly adjusted. Keep the spray equipment and connecting
air lines free of water and oil.

(Fourseal can be brushed or rolled. However, spraying yields a smoother, more consistent finish.)

Gel Time: 15 - 18 Minutes- 2% MEKP @ 77º F. Tack Free: 1.0 - 1.5 Hours

Application guide
Fourseal primer can be sprayed as supplied, or thinned with lacquer thinner up to 33%. 
To catalyze, use a brand of Methyl Ethyl Ketone Peroxide (MEKP) specifically designed for gel coats.

Do not catalyze at levels below 2% or above 3% as this may result in curing problems or other physical defects.
