I use the Revell glue the blue despenser with a needle like end.
For thicker filling in type glueing I use the cheap Revell stuff that comes in a tube. I get both of them from the local toyshop that sells revel kits and GamesWorkshop stuff
I also use super glue of various types, and white glue for canopies. White glue is the stuff you used at school and it dried clear (we mostly painted our hands with it) water soluble and you can peel it off if if needs be.
For filler I use Tamiya basic and Mr smooth putty, and for 1/55 chunkies I use good old 2 part car body filler from Halfords.
Apoxies are a thing of choice.. I use DevCon as its hard setting and very strong. It does pong a bit but I got loads of it where I used to work so I guess when im done I will use Araldite instead
