RE: Silk
I've had good luck with the silk fromThai Silks (see link in earlier post above). Either the 'Paj 5mm" or the "Paj 4.5mm" work well....probably the latter for your smaller airplane. Put it on wet, don't stretch it, just pull enough to get the wrinkles out, and let it dry, then dope it. It can warp a lightly built wing if stretched too much when initially putting it on. I've had a love affair with silk covered planes since about 1950 or so......so good luck!
