I’ve come to rely exclusively on J-B Weld Epoxy when I need serious bonding power. It is essential for large, heavy resin or metal kits but works great in any joint where superglue isn’t cutting it. Mix a little bit of parts A and B (White and Black) together on a pallet and then apply with a toothpick or paperclip. J-B Weld takes 4-6 hours to cure so you need a way to hold the parts together while it does. “Quick grip” clamps, rubber bands, and super glue (for quick short term bond) are your friends. Pro-tip: I sometimes also use a tiny little ball of greenstuff for temporary hold in troublesome superglue and J-B Weld joints. Mix it up a little more yellow so it is extra sticky. This stuff is on the messy side, but it wipes off pretty well with a q-tip or paper towel. The cure-time is the main downside but when you need it, nothing else will do.
In summary, If I’m gluing plastic to plastic (styrene, that is), I use plastic cement. For most other applications (resin, metal, etc.) I use super glue. When super glue isn’t cutting it, I turn to J-B Weld.
