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.
