Hi guys, I was wondering if you might have some recommendations. I need glue(s) for the following applications:

Tamiya model parts > 6061 aluminum
Tamiya model parts > Brass
Tamiya model parts >Copper

I think polystyrene is what's used for most model kits??

I'll be working in fairly small scale--many of the plastic parts only being 5-6 millimeters in size. I don't want them to ever risk falling or getting broken off of the metal they're glued to so shear strength is important as well as longevity. Also don't want to have to work with anything that will leave any thick blobs behind which would cover up part details... any recommendations? Thanks!

Depending on how much grip you need and how quick you need it to set you have the choice of ;
PVA (wood glue) which is cheap with no serious fumes, weak joint but depending on how much strength is needed can be ideal.
Super glue (crazy glue in the USA I believe) quick setting, sticks anything to everything, fumes are not nice, strong bond but weak in some plains.
Epoxy which has more brands and types than you can poke a stick at, fumes and skin contact are bad news, can be very quick setting, creates the strongest bond in all plains.
Gator Glue is a cross between PVA and superglue and is also an ideal choice.

Super gluew or Epoxy......
