I use this glue " super phatic" same as white glue but better dries fast and it's flexable, fuel resistance, cleans with water etc. The only down side is it will not sand well and dope paints don't stick well.. Used for years on my control line and I can say it holds. The best thing is the needle allows you to just add what you want where you want it.

Just don't know why it's never mentioned here before?
