Which glue should I use to bond metal objects like Brass coat hangers? Super glue just seems to break easily. Any suggestions?

JB Quick, it sets in 4 minutes and cures much quicker. But yeah...JB Weld (Just asl for JB Quick Weld) or pick up a micro torch for a couple of bucks (5-10 dollars) and some saftey silver and learn to solder. Fire! fun! What's not to love?

I have used a butane torch to solder some slot car stuff, but people complained about the smell :?

As sidewinder said soldering work to, and in my opinion is the best way.

This list would get you a good start in soldering.

Acid Flux
40watt Weller or Unger soldering iron
60/40 Solder

You can use a electric soldering iron to solder heavier stuff? Huh? I never would have guessed. I use a pencil torch for small stuff but I use my OXY/MAPP torch for bigger stuff. 60/40 solder is great but I still like brazing (just because its more fun) or even gas welding. If you really want to make sure nothing ever comes apart, Harbor freight tools has a nice 115 volt arc welder on sale for $79, or a small mig on sale for $118.

I've been reading about the JB Weld stuff and JB Kwik and I picked some up. I tried gluing a small piece of metal to a piece of plastic and it never holds. Maybe I'm not letting it set long enough but I managed to separate the metal from the plastic twice now. Is there something better for bonding plastic to metal? I was trying to weigh down my ZZ by adding a nice piece of steel to one of the spare rear spoilers I had laying around.

You need to take some fine grit sand paper and scuff up that area of the plastic. Get rid of the shine to it, and clean it with alcohol ( Bacardi 151 leaves a residue, though :-D ).
The plastic still has small amounts of residue from the mold releasing agent when they are formed.

I had similar problems with just glueing plastic to plastic, too.

i'd use superglue personally, and scuff the surfaces as ibj suggested.

I scuffed the surface of both the metal and the plastic. Maybe I should do the alcohol wipe on it since I didn't try that.

The car just so happened to be in the wrong spot, at the wrong time, when I poured one for the homies that have passed away. :(
