I've used this for so many things... It's good for installing clear parts because it doesn't shrink like white glue, doesn't craze like super glue, and doesn't dissolve plastic like model cement. It also works well for simulating water or other liquid in small quantities (like buckets). It makes a good gap filler in places where you can't sand (like next to important detail) because it flows out and sets with a smooth, non-shrinking finish. It can be easily smoothed with a finger or tool dipped in rubbing alcohol. Rubbing alcohol will also clean it off without damage to the plastic, if it hasn't set yet. Does not sand well, so not recommended as a general purpose filler. It's great for model rocket fin fillets as long as you don't let it run all over. It's not the strongest adhesive out there-If you're building a high or mid-power rocket, use 30 minute epoxy for structural joints.

I mainly use for rocket building, but find it is useful to have around for a variety of household repairs. I love this for setting fins and other detail work where you want a fast set. It's easy to get lazy and use this for everything, but it does not stand heat well, so use with care on motor mounts. I will use a small amount to set fins, then use 15 or 30min for fin fillets. I suggest 30min for motor mounts or JB Weld which will handle the heat better.

I use this for field repairs when CA won't cut it. Also for building on components where you need to keep them aligned but can't really put them in a jig or keep them clamped together (foam wings). otherwise I tend to use the 30 minute for most of my building. Mostly use this on RC airplanes. its got its place, and if you build you will find this is a good one to have.
