Hey guys going to start putting silk span on wing what order do I go by, one side top and bottom then other wing half. Or do I do both bottoms then both tops.
I'm using silk span and Randolph dope.
Thanks for the input.

Cover both sides of the wing and keep the covering moist. When finished hang the airplane by the leadouts to dry. Otherwise the top will dry faster than the bottom and may give you a warp.

It's been mentioned before to cover both sides at the same time.
I have absolutely no idea how this can be accomplished when you have silk hanging over the edges?
My efforts have paid off, I'm now silking with great results, tight as a drum and no warpage. I also use a "mist" bottle to keep the silk damp.
Pull like a mother on the tips to tighten the silk and yes, I use pins. I'm still doing it the way I learned in the late 50's.

We used to try to cover straight wings like the VooDoo with a single piece of silk to minimize seams and wasted material. We covered the top first and had the overlap at the bottom of the trailing edge so it wouldn't show much with the clear dope finish.
Now on bigger models I prefer four seperate pieces with the top done first to get the overlap on the bottom. After doping the wood framework well, I install the silk with only a minimum outline of thin dope. I don't dope the open bays until the dope and water has dried on all four panels.
