Welcome to a better avenue of building plastic sailing ships. I very rarely use plastic masts and spars anymore, they are just too much of a hassle when it comes to rigging. One piece masts and spars look out of scale and the two piece masts end up splitting apart if too much stress is put on them. I like to use the plane method and use the small plane by Exacto to taper the ends ot the spar, then sand to the final shape. With regards to adding details, there are millions of ways to do bands, caps, and covers by using solder, wire, plastic strips, washers, or aftermarket fittings that is covered in any scratchbuilding book. As far as painting, depends on the scale. On the larger 1/96 scale models, I use wood laminates on the deck and tend to replace the gratings and other fittings with wood and brass, so there is a good balance between painted and natural wood. On smaller models, I tend to paint everything in order to keep a scale balance.
I use four types of adhesives. CA for moderate bonding, Testors liquid like what you have for tacking and temperary fits, 5 min expoxy for the masts or for bonds that will take a lot of stress, and Gorrilla glue, which I was just introduced to, which I may be using instead of the epoxy since it does a much cleaner job for bonds to wood and plastic and wood to wood.
