What adhesive do you guys use to attach vortex generators that fell off? That loctite 330 stuff is really expensive and doesn't seem to come in very small quantities. I only need to attach 3.

I use gel-type cyanoacrylate (super glue). Works great.

Thick super glue or 5 minute epoxy.

Super glue it is. Thanks

If you call Microaero, they have repair kits and small tubes of Loctite. They can also send you a few spares of the VG's so you have them for next time.
