SilverTip EZ-Fillet
EZ Fillet is a wood flour-filled two-part putty specifically designed for stitch-and-glue wooden boat construction. Its ketchup-like, self-leveling consistency allows it to be measured by volume or weight. The resin (part A) is brick red in color while the hardener (part B) is a deep, dark green. A rich brown wood tone results when the two parts are combined indicating complete mixing. The putty thickens after mixing to form an easy to spread, thixotropic compound, which stays put and will not run or sag. EZ Fillet has been designed for superior strength and workability and can be used by itself to create smooth cosmetic fillets or as a structural fillet when combined with fiberglass cloth. EZ Fillet can be applied by spatula or caulking tube. A convenient pastry bag technique can be used by snipping off the corner of a plastic food storage bag and filling it with mixed EZ Fillet. Adjust the size of the hole to deliver just the right amount of EZ Fillet.

Recommended Uses:
EZ Fillet is specifically designed for both cosmetic and structural fillets in stitch- and-glue wooden boat construction.

Use at a simple 2:1 volume ratio. Once mixed and applied EZ Fillet cures overnight to an exceptionally strong fillet, which may be sanded for fiberglass tape. Alternatively, the tape can be applied after EZ Fillet starts to get stiff. Use SilverTip Laminating Resin for this purpose and work EZ Fillet under the wet tape for a smooth, bubble-free composite. Another way to achieve a smooth fillet is to let EZ Fillet get fairly stiff and then smooth with a rag soaked in paint thinner. Sand lightly after curing before applying tape.

Available Color:
Resin (part A): Red
Hardener (part B): Green
Mixed Color: Brown

I have been trying out the System Three EZ Fillet product- this stuff is great! Mixes up quickly, makes a perfect fillet, cures fairly quickly - I will be using it for all my filleting and many gluing applications from now on!
