JB Weld is great stuff, but I just never felt confident enough in it to hold things like that together. I tried several aluminum brazing rods and really had no success (surely my fault - other's must have), but I found an HTS-2000 supposedly 2nd generation rod and it worked great for me.

Or possibly joining tubing together. The ability to contour and smooth this product would seem suited here where air flow is an issue. But I don't know if it would stand up to all the rigors (vibration, heat, etc.) Just throwing it out there since JB Weld is smoothing the ports on several intakes out there.

I saw some in HD that claims good for temps up to 450. I'm hesitant, but this stuff seems to be a cousin to JB Weld. Bryan JB weld ( and similar) is wonderful stuff that adheres to almost anything, and is amazingly strong. So if need things to hold together and make a good seal - great. But if you need real strength, anything that just adheres to the surface is not going to be as strong as a good weld. So consider your application, and what it has to do, and then decide.
