Goop is some of the most universally incredible stuff around -- been around for longer than any of the new stuff like GG.
Plastics - while you don't say what MATERIAL (it's hard to know sometimes) it is you are gluing, they are typically going to be non-polar. For example, what you have in a remote is probably going to be ABS or it could be a high impact polypropylene.
Not being "polar" essentially means it doesn't have any electrons to give away or any empty shells to accept one. Special techniques are used to treat these materials in order to make them more friendly to things like paint and glue (including such simplicity as treating it with a flame!) - and electron beams or adding peroxides to the molten mix or to the reactor as it is made.
SO -- this is why the stuff is so difficult to glue, paint, or pretty much anything else (but also makes it impervious to ammonia, Drano, etc., etc.).
The solvent glues with a 5 minute set (like Gorilla, the new 2 type Liquid Nails "Perma" and others which are hitting the market), use the Fit, Pull Apart, Refit method - and adding just a miniscule amount of water actually helps (read your instructions) the bond
as the solvent is evaporating.
Bad thing is that these glues have no torque strength against twisting, etc., because the glue is mostly bonded to itself! Hanging - that's one thing, but if it was a "car door flap" - it could never withstand the pressure of the linkage.
CA (Krazy Glue) in gel form might be your best bet- but you won't find any of the commercial accelerators unless you go to a model shop or hobby shop. These are little more than water with an alkaline agent. The faster the acidity of the glue vanishes, the faster it sets up. Water dilutes it, so it sets up faster.
Water will ideally do that (use a spray mist bottle), and even better yet, add a little baking soda, and make sure it is in solution (stir it well). this will cause it to rapidly set.
Make sure you're fingers are clear. Like WAY clear.
