Dude.... it sounds to me like you just need to bite the bullit and buy a new set of hoops. It sounds like the spoke eye-lets are stripped, and even with a dab of loc-tite wouldn't hold.
I'd suggest trying a different manufacturer, or replacing all the eye-lets on your current rims. A friend of mine had a wheelset that was the same way, no matter what you did to it, it'd come back in like 2 hours with approx 6-8 loose spokes. It was rather ludicrous.
Your best bet is to probably just buy new rims, and get those current "Voodoo infested" rims off your bike.
