Any superglue (C/A) will do. DON'T buy Tamiya's, wayyy too expensive. You're mainly paying for the brand name
. I know a lot of people use the cheapest they can find but I use 3m's stuff, it comes in a red or grey protective bottle where the tube itself is inside.
Red is the liquid type, grey is the gel type.
IMHO it lasts longer due the the bottling design.
I've had a red tube last for over a year without hardening. thickening up but not hard.
The only downside of using C/A is the it leaves a hazy white smoke on nearby areas when gasing out... so try to keep a steady air flow on it when its drying...
HTH,
