Whether you are building a complete resin kit, or using an aftermarket kit to convert a standard plastic kit, you will find that the resin parts are likely to need more work on them than the more normal injection molded plastic parts that you may be used to. Resin parts are cast from a liquid and may well come still attached to the casting block. If this is so, then they need to be separated. If the attachment point is thin then it might be separated with repeated passes from a sharp hobby knife.
Super glues come in a variety of thicknesses. Also available are activators to speed-up setting time and debonders for when you inevitably stick your fingers together.
Standard polystyrene cement which is perfect for conventional styrene models is absolutely useless for resin parts. Poly cement works by slightly dissolving the styrene plastic, but it wlll not dissolve resin and so will not work at all. When gluing resin parts to each other, or to plastic, you will need to use either two-part epoxy glue or cyano (superglue) adhesive. Both of these work well, so it is down to individual preference.
