I've tried several, and my favorite so far is Zap-A-Gap. It's available from Junkyspot and hobby stores. I like it for several reasons.
- It bonds in 15 seconds or less.
- It bonds metal to resin, resin to resin, wood, plastic, fabric, glass, ceramic, and much more.
- You can use it to fill in gaps in projects, in addition to bonding.
- It can be removed with acetone.
You only need a few drops, and you'll need to work fairly quickly. Make sure you have steady hands (not too much caffeine, mind you).
