Kennedy Jr: I use Epoxy most, Tamiya bottled second, Tenex third, CA 4th, and GS Hypo 5th, I'd say. Each one has its own tricks to use it successfully. But I think you shouldn't give up on Epoxy yet.
I couldn't get Epoxy to work either, but after reading this forum and emailing some folks and reading a bit I decided to give it a shot and guess what after some messing around and experimenting EPOXIES REALLY RULE!!!!
--Get Devcon 5 minute epoxy. Devcon is really good! Don't get anything else, don't get the generic Ace hardware 5 minute one for instance. For me that Devcon 5 minute one is the very best. It comes in plastic bottles that don't get yucky/slimey after a few uses. It's easy to mix and store. It's not too expensive. It dries clear.
You can order it online if your local hardware store doesn't carry it. That's what I ended up doing. It's worth the extra trouble.
--Get a 8 1/2 x 11 piece of white paper, like what you'd use at work in a printer. It can already have been used to print something (better for the environment to use something you'd otherwise pitch)
--Put equal size beads of the 2 parts right next to each other, and then with a toothpick stir them together "with vigor". The beads don't have to be exactly the same size but they do need to be pretty close. The beads can be small--you can't use much devcon in 5 minutes so you'll learn to make your beads the right size after you use it for awhile.
--Don't put your parts on the white paper, ever. That way you won't accidentally drop your parts in some epoxy. I usually work with 2 sheets on my bench--paper for mixing/applying glues and paper towel for the parts, and the two never meet.
--Prep your parts really well! You **must** remove all chrome and paint before you join because Devcon won't stick to either (especially chrome--it really doesn't stick to that well at all). In fact, I have found this for pretty much every kind of glue, except maybe CA + accelerator in some cases.
