Are the surface(s) clean and dry? No rust, corrosion, etc? Also, it won't work if the surface is too cold.
JB Weld...your experiences?

Another recommendation I have is use friction/hockey tape over the jb to help hold its form while drying. So if you are welding somthing all the way around, I will apply and rotate the part for a few minutes until it doesnt run as much. Then lightly wrap the tape around the outside to keep gravity from having its way with the part.

Love the stuff, Ya' gotta' pick your battles though.
This one's a K Zildjian / Istanbul, to many musicians it's the Holy Grail of cymbals.

I think who ever though that sh!t up should be tared and feathered then hung. I get more aluminum fuel tanks that guys thought it was "good enough" and the diesel eats it alive then yeah got to get it all off or it really pisses the TIG machine off...

I have used JB Weld twice:
Once on the motor mounts of a lawn edger who's engine bolts used to work loose and fall out all the time. I filled the threaded mounts with JB Weld, drilled them out, and tapped them. After 48 hours I reinstalled the mounting bolts and torqued them to spec. This repair has lasted two years of frequent use and I've never had to retighten the bolts. An inexpensive repair and a sucess.
More recently, I nicked a PVC irrigation line while tilling: this nick later resulted in a bad leak. The nick was located right in the middle of a T-fitting and would have required a new T-fitting, three inline couplers, and six cuts to the three irrigation lines connected to this T-fitting, not to mention digging up a major part of of a freshly planted garden. So I decided to try some JB Weld to repair the nick. I sanded the PVC T-fitting with 80 grit paper, and then applied about an 1/8" layer of JB Weld over the nick and surrounding area. After 48 hours, I tested the irrigation circuit... it held (at 65 PSI water pressure) and the repair took less than 5 minutes to accomplish. I think I can call this another sucess, at least in the near term. Will have to wait and see how the repair holds up over the next 5-10 years.
