Hello,
I lay the piece of Silkspan over a towel and then spray the water over it. The towel eliminates the excess of water.
Lay the silkspan over the wood and brush 50/50 dope/thinner (I use nitrate).
There shouldn't be any wrinkles but if you got some, take a small cotton ball, damp it with dope and rub it lightly over the wrinkle.
Claudio.
