I'm like the others for the most part.
1. Tamiya liquid cement for the plastic stuff. I also use Testors liquid cement occasionally. It doesn't set up quite as quickly as the Tamiya stuff.
2. Superglue (cyanoacrylate adhesive) for PE and resin parts, and occasionally some gap filling.
3. 2-part expoxy for heavy duty anchoring projects. It's also good for attaching weight to the nose of an aircraft.
4. Elmer's white glue for clear parts, and occasionally a little seam filling in right angle situations. I also like Microscale's Krystal Kleer.
