CA gel will work to bond styrene to wood. This is what I use. There are cautions to observe: one is to use the gel not the thin CA (at least in my experience). The other is CA can and will melt the styrene if you use too much. Use small dabs of the gel for best success. CA thin is hard to control quantity and will almost always end up melting the styrene If too much is applied. Another trick using sheet styrene on curved surfaces…use a hot air gun to heat the shape and form it to the curve…such as a mast. The formed shape takes away the stress of the shape trying to spring flat as you are gluing it down. CA gel works better when the styrene lays flat to the surface and you are not fighting the shape springing open. Anyway…this is what has worked for me. I use a lot of styrene shapes in my ship models…especially for moldings around stern quarter windows and the shaped moldings along the length of the hull.
