Hi Brian,

The silk weights about 20 gram/m/2.

You can find it here:

I have experience with glass and epoxy and with thin rice paper glued with sanding sealer.

I find that this method – silk glued with sanding sealer is the best.

The silk is much more dense then the fiberglass although they weight almost the same, so you need lese epoxy or sanding sealer to fill it.

I found that gluing the fabric with sanding sealer and not with epoxy is much much better!!!

You don`t have to wary if you sand truth the silk (this is not the case with the other methods).
All you have to do is just apply some sanding sealer and sand a little bit the aria; this is because you do not use two different materials (sanding sealer and epoxy) and because the silk is organic material like the balsa wood.

About the silk compare to glass and epoxy for tensile strength (stiffening the part) and for ding resistance (hardening the surface); it looks to me the same.

Best regards,

Isaac Najary
