Thanks Wayne!
I suppose the regular JB-Weld is stronger than the JB KwikWeld which is sort of a 6 minute JB-Weld.
I'm gluing a small brass with nickel coating, nut, to styrene so I can attach a part with a screw.
I mentioned in another thread that I used Devcon 5 Minute Epoxy and the nut didn't hold.
