Hi Ken, I just use it direct from the bottle and put a small bead on the ribs and a larger bead on the spars, generally there is enough humidity in the air to activate the glue so I do not wet the wood. There's usually about 15 minutes of time to do the one side if the humidity in the house is not too hi but if the glue starts to foam slightly your time is very short to get it pressed. I do only one side of the panel at a time, by placing the skin being glued on the bottom gravity will hold the glue in position at the skin / rib joint.
