Tamiya Green Cap for all styrene joints that can easily be reached with the brush after being put together.
Tamiya Orange Cap for all styrene joints that must have glue applied before going together.
Gorilla Blue Cap CA for metal to plastic bond where there is very little surface area to bond to (such as edge-mounted PE parts and wire) and you can't easily stabilize the joint.
Bondic UV curing glue for the same purpose as Gorilla Blue Cap CA, but in situations where the joint can be easily stabilized before hitting it with the UV light. It cures completely transparent, which gives it a big advantage over CA.
Pledge Floor Care for smaller PE parts that essentially lay flat, such as seat belts and instrument panel overlays. No other glue matches it for transparency. Put your clear coat of choice on afterward and it will look like it was built with the part it was attached to. It is also fantastic for attaching HUD glass to HUD frames...keeps that perfect, distortion-free transparency.
Devcon 2-Ton Epoxy for attaching clear parts or attaching things such as canopy frames to canopies. Unmatched transparency when compared to other, traditional canopy "white" glues, and it makes a stronger, more permanent bond. Also makes great lenses for aircraft lights and weapons sensors. As far as fogging and fume fears that a lot of people have about epoxy, when attaching clear parts or making lenses, you're using such a tiny volume of epoxy that there isn't any significant exothermic reaction...that only happens with larger volumes of resin and hardener. It is 100% safe in these tiny amounts. I also use it for attaching larger PE parts with larger surface area, as well as it being my go-to for attaching Quinta Studio 3D-printed decals.
Apoxie Clay has come in handy recently as an adhesive/filler for attaching large resin parts to styrene where the mating surfaces aren't quite perfectly matched. Any excess that gets where you don't want it can easily be removed with a damp Q-Tip prior to curing. When it cures, it creates an extremely strong bond that resists shearing and cracking.
WHEW! Hopefully I didn't miss anything.
